-:r :d..d:d:-d:Silicon carbide rod
-:- ..D type silicon carbide rod is the most widely used model.
-:- ..Silicon carbon rods are non-metallic electric heating elements. They are made of high-purity green hexagonal silicon carbide as the main raw material and recrystallized at <℃ high temperature. The normal operating temperature can reach <℃ and can be used continuously under reasonable use conditions. Use in air for more than < hours does not require any protective atmosphere. Suitable for various electric furnaces and electric kilns.
-:- .. Due to the high operating temperature, silicon carbide rods have the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, fast temperature rise, long life, small high temperature deformation, easy installation and maintenance, etc. and have good chemical stability
