sic heating element

Short Description:

Sic heating elements are made from quality green SiCpowder, which added to some additivies according to the materials proportion.Silicon carbide heating elements are non-metallic products. Compared withmetallic heating elements, they have a series of characteristics, such ashigher temperature, antioxidation, anticorrosion, increase temperature fast,low coefficient of thermal expansion and so on. Therefore, they are widely usedin electronic and magnetic material, ceramics, metallurgy industry ...
