Alumina Ceramics:
Alumina Ceramic special refractory materials are new inorganic non-metallic materials developed on the basis of traditional ceramics and general refractory materials. It has the following characteristics: high melting point, high purity, good chemical stability and thermal shock stability. Special refractory materials include high melting point oxides and refractory compounds and cermets derived therefrom, high temperature coatings, high temperature fibers and reinforcing materials. Compared with traditional ceramics and refractory materials, special refractories have high purity, high melting point and good electrical, thermal, mechanical and chemical properties. Therefore, they can be used in high-tech, precision and sharp technology. In terms of manufacturing process, raw materials generally pass through. Pre-burn. In addition to the traditional methods, new processes such as vapor deposition and hot pressing are also used. The molding material is a micron-sized micro-powder, which can be made into a thin product (translucent) under high temperature and protective atmosphere.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
