Ceramic is one of the most important materials used for ages, and its use has become widespread with the development of techniques for designing and manufacturing ceramics. The word &#;ceramic&#; is a Greek word (keramikos) meaning potter or pot maker and refers to materials obtained from raising high temperatures.
And when we look around we find ceramic material almost everywhere, the many features of ceramic make it the perfect choice for many uses. In this article, we will discuss the advantages and uses of ceramics and everything you need to know about this material, including components and types.
Ceramic components and How are they made?
The composition of the ceramic material is one of the complex chemical structures, and it is more complex than the mineral structures, and the ceramic material is a non-metallic and inorganic material, and it consists mainly of clay and earth materials (clay, feldspar, silicate sand and lime...) in addition to chemicals such as oxide Iron, sodium hydroxide and some colourants.
When manufacturing, clay is first prepared, which is the basic material on which the ceramic design is built, and the basic body is obtained. Previously, the makers used to dig, extract and shape the clay manually, but now with the development of industry, manufacturers are buying ready-made clay objects from local suppliers, Until this stage is bypassed without trouble and loss of time.
At this stage, the materials to be used are described, and these materials are tested and processed according to the evaluations and specifications to be used.
Secondly, the materials used are ground in a huge mill to produce a substance called quartz, and then this substance is placed in a closed machine with a very high temperature that contains water. This process helps to dry the material and prevents internal contractions of the material making it one solid material that is easy to shape.
Some ceramic products are subjected to a crystallization process, such as products used in electrical insulators, dining utensils and tiles, in addition to a final process, which is the polishing process to suit the required geometric shape.
Among these stages is the process of decoration and shaping, as the ornate shapes produced from ceramic material have a distinct shape from other materials.
The Features Of Ceramic
Ceramic is the product of the integration of several materials, and therefore the materials used can be controlled according to demand and use, so chemicals have been used that control the strength, hardness and properties of this produced material.
And here are some of the most important features of ceramic material:
Its hardness and high resistance to pressure and fracture.
Its resistance to water and cleaning materials, is chemically inert and does not affect and does not interact with the chemical elements used in cleaning materials, and its outer layer is smooth and does not contain any dirt or stains.
It is resistant to dust, moisture and abrasion, which makes its life longer than that of marble and other building materials.
Its cost is not high compared to other building materials, despite its high strength and quality.
Low coefficient of friction and makes it cleanable and does not require special materials or methods for cleaning, and that is why it is widely used in bathrooms and kitchens.
It can be shaped and decorated in many different shapes, and a glossy layer can be added to its outer surface, which adds a wonderful lustre and an attractive appearance.
Types Of Ceramic
As we mentioned, ceramic is a material that results from mixing several materials, and this facilitates the production of many different types of ceramics, and they were produced according to the properties required for use.
There are 3 traditional types of ceramics:
1- Porcelain: includes glazed or unglazed utensils, used in the manufacture of cooking utensils, vases, cups and tiles, and is usually white.
2- Claystone: It is dense pottery that is burnt to high degrees, and is stronger than other types.
3- And there is another type which is a highly heat-resistant material, and it is a strong material and is used in bathroom and kitchen tiles and some sculptures, and is used in some engineering applications.
A type of ceramic is called advanced or engineering ceramics:
In the manufacture of traditional ceramics, some problems appeared due to the pores and cracks that result when combining materials, and with the spread of the use of ceramics in modern applications (industrial, electrical, thermal and mechanical applications.....) ceramics were developed and engineering ceramics were produced by reducing the resulting holes and cracks to appear a stronger and more resistant form.
The Uses Of Ceramics
With the many features and the development of ceramic manufacturing techniques, its uses have varied in many places, and there are many applications, and we will mention some of them:
1 - Ceramic is used in construction as a basic element, especially in kitchen and bathroom tiles because of its durability and resistance to water and detergents.

2- Crockery and kitchen utensils.
3- Toilets and basins.
4- The high resistance to heat made ceramics one of the materials used in the mechanical industries, as it is used in the manufacture of turbines that operate at a large temperature, in addition to its entry into the industries of modern spacecraft.
5- Its high resistance to corrosion and its insulation made it also included in electrical engineering applications, and it is used in electrical insulators and some electronic devices.
Things to consider when choosing ceramics
When choosing ceramics, several things must be considered based on the place and influencing factors:
: The size is chosen according to the place to be used, and it is usually square or rectangular.
: It must be shaped accurately, its edges are perfect and without breaks, and it must have a flat surface.
High water absorption ceramic: This type is characterized by a smooth surface and is also characterized by not transmitting sound between layers, and it is used in bedrooms and corridors.
Ceramic with low water absorption: It is characterized by closed pores, resists frost and is used in floors and walls of kitchens and bathrooms, and is used in outdoor areas exposed to rain and moisture.
: Where the ceramic compound must be experienced, when installing ceramics, the dimensions and spaces must be maintained very accurately.
: Choosing a suitable colour for the place to be used. Some prefer blue and white for bathrooms and kitchens, while in bedrooms, different colours are used according to demand.
: The coating is very important as it gives the exterior and final appearance of the ceramic, and it must be chosen carefully to resist corrosion and protect the lower layers of the ceramic from cleaning materials and external factors.
Ceramic Prices
As we mentioned earlier, ceramics are not considered high costs, and their prices vary according to demand. Many factors affect the price of ceramics, including corrosion resistance, paint quality, materials used in its manufacture and other factors.
Finally, ceramics is the most important building and design material in our time, so that it has been of great importance throughout the ages. We find it used in construction and making pots and pottery since ancient times.
Ceramics have many advantages that we mentioned in the above article. It gives an elegant shape in addition to its suitability in many places and uses. The same group also provides the most luxurious and finest types of ceramics suitable for all needs and tastes.
Introduction
You might not realize it but your life revolves around ceramics. From the ceramic-based electronic components in your computer to the high-end TV you watch, ceramics are constantly a part of your life. Even though you might not understand or recognize ceramics, it doesn&#;t mean that they aren&#;t a vital feature of your day - and the world around you.
Yes, ceramics are everywhere and they have come a long way in the recent years. While once used in just a few industries and on select daily items, ceramics are now located in almost every business in one way or another. And their value only grows as more and more companies find ways to make your life easier with this miracle creation. So what are ceramics and how are they used? How do they make your life so much more manageable?
What are Ceramics?
In the most technical sense, a ceramic is a specific type of non-metallic material that has been formed and then solidified by an intense heating process at radically high temperatures. Ceramics are typically brittle, hard, and corrosion-resistant and often very strong. They look and feel like a combination of glass and cement. Currently, the term "ceramic" has taken on a broader definition, encompassing materials such as glass, advanced ceramics, and certain cement systems.
While traditional ceramics are clay-based and rely on clay for their creation, modern-day ceramics are using new materials that aren&#;t clay. Instead they used materials that are based on oxides or non-oxides or combinations of the two such as alumni, zirconia, carbides, borides, nitrides, and silicides, just to name a few.
The Properties of Ceramics
The most essential feature of ceramics is that they are refractory: they are rough-and-tumble materials that can withstand a lot of damage in both ordinary and unusual circumstances. Consider this: most of us tile our kitchens and bathrooms because ceramic tiles are durable, waterproof, scratch-resistant, and look excellent year after year.
Engineers also use unique ceramic tiles on space rockets to shield them from heat when they return to Earth. From your shower to the stars, ceramics are used in all sorts of ways because of their strong, distinct properties. Here are the most notable attributes of ceramics:
They have high melting points, which means they are heat resistant.
They feature great hardness and strength.
They have considerable durability, which means they can last for decades.
They contain low electrical and thermal conductivity.
They have chemical inertness, which means they're unreactive with other chemicals.
Types of Ceramics and How They Are Used
Classic, time-tested ceramics that have become a part of everyday life include bricks, glass, porcelain, cement, pottery, tiles, and concrete. Despite the fact that they all have diverse applications, we may still consider them to be general-purpose materials because they are used in many of the industries that make the world go around.
Take a look at the kitchen in your home. It is filled with tiles and glass and porcelain that is ceramic-based. The same is true for your bathroom too. Traditional ceramics like these are old materials that our predecessors would know well, and they've steadily gained in popularity as the years have passed. Advanced ceramics, on the other hand, are materials that have been developed during the previous few decades for very specialized uses.
The most notable examples involve silicon nitrides and tungsten carbides, which are made for making extremely hard, high-performance cutting tools, but they also have other applications. Metal oxides, carbides, and nitrides are the most common contemporary manufactured ceramics, which are compounds formed by mixing metal atoms with oxygen, carbon, or nitrogen atoms. While you might not know of these ceramics off the top of your head, they are surely influential on many items in your home and many industries that help serve you throughout your life.
How Are Ceramics Used
We've seen that there are numerous different items that may be classified as ceramics, from glass and brick to porcelain and cement. Not surprisingly, there are quite literally thousands of diverse uses for ceramic materials in anything from aerospace to house keeping.
Plane jet engines, for example, are gas turbine devices that function by burning fuel combinations at high temperatures to produce a flaming exhaust that propels a plane into the air. The requirement to withstand extreme temperatures explains why ceramics are frequently used in engine components. Thousands of ceramic tiles were employed aboard the now-retired NASA Space Shuttle to save it from bursting into flames on its journey down to Earth from space for the same reason.
In fact, it was faulty ceramic tiles that caused the tragic loss of the Space Shuttle Columbia in . Ceramics are also commonly utilized on building sites as tools. Whether you're cutting glass, crushing concrete, or sawing through industrial brick material, engineering ceramics will help shape more traditional ceramics, and will perform better and last longer than steel-based tools. Ceramics aren't necessarily cutting-edge. Actually, we often overlook them, particularly when they're hidden behind electrical and electronic equipment.
Magnets are found in anything that has an electric motor and they're frequently composed of ferrite ceramics. Ceramics are also used in the electrical systems that heat and cool us in our homes. You will often see ceramic insulators in overhead powerlines. You will also see ceramics in your home, on the stove top that is producing great heat to make your meals.
Conclusion
Ceramics have advanced over the years and are able to be used in a variety of different products and industries that help make your life so much easier. Your kitchen, your bathroom, and the power that flows through your home relies on ceramics. But ceramics are used for far more than just that.
In fact, the rocket ships that are flying through the stars need ceramics too. The wide range of uses for ceramics prove just how important they are. For years now, they have helped the world go round and as more time goes on, ceramics find more and more ways to make life easier.
