The silicon carbide 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 , silicide 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 various high temperature electric furnaces and other electric heating devices , such as in the industries of magnet , ceramic , powder metallurgy , glass , metallurgy and machinery , etc .
