sic heating element is a kind of non-metal high temperature electric heating element. It is made of selected super quality green silicon carbide as main material, which is made into blank,silicided under high temperature and re-crystallized. Compared with metal electric heating element ,this kind of element is characterized by high-applied temperature, anti-oxidization, anti-corrosion, long service life ,little deformation ,easy installation and maintenance. Therefore, it is widely used in varilus high temperature electric furnaces and other electric heating devices ,such as in the industries of magnet, ceramics ,powder metallurgy, glass ,metallurgy and machinery,etc. chida(at)eheater(dot)cn
