Later found that the use of natural raw materials, completely without silicate, can also be made into ceramics, and more superior performance. Thus, the ceramic family, which has always been dominated by silicates, has changed, and a completely new and modern ceramic that does not belong to silicate is found.The exact said "ceramic" is defined as: the ceramic is natural or synthetic compounds made of powder, after forming and sintering, polycrystalline solid materials composed of inorganic compounds, metallic and nonmetallic elements. Both traditional silicate ceramics and modern ceramics are included in this range.
At present, all ceramic products are commonly referred to as "inorganic non-metallic solid materials".Structurally, common ceramics are complex systems consisting of crystalline materials, glassy materials, and bubbles. The changes in the amount of these substances have a bearing on the properties of the ceramics.The ceramic ancestor is Portland ", also known as the" habit of silicate ceramic ", because the modern ceramic development very fast, people made a lot of experiments to improve the silicate ceramic, continuously improve the content of the formula of alumina, synthetic compounds with many high purity to replace natural raw materials, to improve the strength of the ceramics, the high temperature resistance and other properties.
Tongsudejiang made of clay ware pottery is used to burn the clay, called porcelain ware. Is the ceramic pottery, stoneware and porcelain. Those who use clay and clay the two kinds of clay as raw material, after ingredients, molding, drying and roasting process made the objects can be called ceramic.Ceramics include a wide range, some can be water-resistant, and some can be acid resistant. Widely used in construction, chemical, electrical, mechanical and other industrial and daily decoration. In addition, other materials other than clay products, according to the process method of ceramic made, also called ceramic, such as steatite porcelain, metal ceramic, ceramic capacitor, magnetic ceramics etc.. Widely used in radio, atomic energy, rockets, semiconductors and other industries.
