Explanation

A product made from inorganic non-metallic natural minerals or chemical products through processes such as raw material treatment, molding, drying, and firing. Its microstructure consists of crystal phase, glass phase and gas phase, and the proportion of the three phases varies according to different varieties. ceramics has excellent properties of high temperature resistance, abrasion resistance, corrosion resistance, oxidation resistance, electrical insulation, high strength, high hardness, etc. The traditional concept of ceramics refers to all products processed with clay and other natural inorganic no-metallic mineral as raw materials, mainly including domestic porcelain, architectural sanitary ceramics, display art ceramics, chemical ceramics, chemical ceramics, electric porcelain, etc. With the progress of science and technology, the manufacturing process and use of ceramics have been continuously developed, and various structural ceramics, functional ceramics and biological cemmics with special properties have emerged, collectively known as advanced ceramics, also known as high performance ceramics, fine ceramics, moden ceramics, high-tech ceramics or special ceramics. This kind of ceramics mainly uses high-purity artificial oxide, carbide, nitride, boride, silicide, sulfide and other inorganic non-metallic materials as raw materials, adopts advanced molding and sintering technology, and some products are further processed by precision machining. ceramics are endowed with high temperature resistance, wear resistance, high strength, heat shock resistance, high rigidity, heat insulation, and electrical, magnetic, optical, sensitive, bioactivity and other properties, and are widely used in electronics Computer, laser, nuclear reaction, aerospace, biological materials and other modern cutting-edge scientific and technological fields.
