Silicon carbide crucibles are made from high quality SiC powders. They have little deformation at hightemperature, low coefficient of thermal expansion, antioxidation and anticorrosion, high strength and so on. They are used for powder sintering,metallurgy, glasses and chemical industry.
Sisic ceramics adopt slip-casting technology. The Ceramics have high strength and excellent hardness, wear,corrosion resistance, oxidization resistance and thermal shock resistance, etc. Its one of the most popular refractory ceramics. It can be made to beams, rollers,cooling air pipes, thermal couple protection tubes, sealing parts and special shaped parts
