1. in the material, breaking the boundaries of traditional ceramic to clay as raw materials, special ceramics generally oxides, nitrides, silicides, boride, carbide, such as main raw material.
2. in composition, composed of traditional ceramics clay component of decision and Kiln ceramics from different regions have different textures. Because of special ceramic materials are pure compounds, so the ratio of ingredients by artificial decision, whose nature by the purity of the raw materials and processes, rather than determined by the origin.
3. in the preparation process, breaking the traditional ceramic furnaces as the main means of production lines, the widespread adoption of vacuum sintering, protective atmosphere sintering, hot pressing, Thermo-static pressure and the like.
4. in terms of performance, special ceramics with different special characters and functions, such as high strength, high hardness, resistance to corrosion, electrical conductivity, insulation and magnetic, electrical, optical, acoustic, biological engineering has a special feature, which is at high temperature, mechanical and electronic engineering, aerospace, medicine has been widely used.
