SIC Ceramic Tubes pipe heating element is one type of ceramic heating elements,which use six-party high purity green SiC powder as the main raw material.Silicon is recrystallized under 2200C high temperature to form finished materials.The using temperature up to 1450C under oxidation atmosphere,and constant working life up to 2000 hours.It is widely used in various high temperature electric furnaces and othe electric heating devices,such as in the industries of magnet,ceramics,powder metallurgy,glass,metallurgy and machinery,etc. Protech silicon carbide SiC heater element is a kind of nonmetal 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. Max temperature 1600 deg C.
