Ceramics are materials that are made out of naturally occurring earth or clay. Scientifically, ceramics are defined as compounds of non-metallic and metallic components. There are even manufactured ceramics like SiC, Si3N4 and diamond. However, in modern uses, the broader definition of ceramic would be everything that is not organic material or metal. They tend to be inorganic and are generally used or processed at very high temperatures in a ceramics company. At a ceramic manufacturing unit, one can find that these products are manufactured by the act of heat on earthy-natured raw materials. The branch of understanding that deals with the manufacture and the treatment of ceramics is known as ceramic engineering.
Different Varieties Of Ceramics
There are different varieties of ceramics that have been classified into four categories and they are as follows:
- White Wares- These include items like sanitary ware, decorative, wall tiles and tableware. Perfect examples of such ceramic products include porcelain, stoneware, earthenware and bone china.
- Structural- These products include floor and roof tiles, bricks and pipes.
- Fine or Technical ceramics- These include products like the tiles used in space shuttle programs, biomedical implants, ballistic fortification, nuclear fuel uranium oxide pellets, jet engine turbine and missile nose cones.
- Refractories- These are steel and glass building crucibles, kiln linings and gas fire radiant.
However, there is one type of ceramic that every ceramics company looks forward to manufacturing and that is Alumina Ceramic. Below, we will be having a detailed look at this ceramic product.
About Alumina Ceramic
Alumina ceramic provides top quality insulation properties along with great resistance for electricity. It is also known for its high hardness but possesses comparatively lower fracture toughness and strength. It is one of the most mature varieties of engineering ceramics. It is available in white but there are varieties that can also be pink. It is worth noting that alumina ceramics get their color from the contamination in sintering additives and raw materials.
Superior quality alumina ceramics are perfect for environments where proper resistance to wear and tear and corrosive substances is needed. Such ceramic products can even be used in place where temperatures tend to be very high. Alumina ceramic is known for its thermal stability and thus it is highly resistant to high temperatures. It is also to be noted that this form of ceramic possesses the ability of resisting water, tear and heat and thus it is considered perfect for the manufacture of different elements that should be wear resistant.
Out of all the different forms of engineering ceramics, alumina ceramics is considered the best and there are obviously some good reasons behind this. Alumina is the best electrical insulator and is resistant to high electricity. Alumina ceramic also tends to be corrosion resistant and when blended with additives, it can work with enhanced properties. A ceramics company produces these products in different sizes and shapes by using different types of processing techniques such as machining and met shape.
