1550 ℃ Silicon Carbide Electric Heating Element



SiC Heating Elements Introduction



Silicon Carbide Heating Elements is a kind of non-metal high temperature
electric heating element. Silicon Carbide Heating Elements is made of selected
high quality green silicon carbide as main material, which is made into blank,
siliconization under high temperature and recrystallized. It is the most
popular type of economical heating element capable of operating under hot and
rigorous environments.

influence on the Rod
Ammonia 1290 3.8 The action on SiC produces methane and destroys the
protection film of SiO2
Carbon dioxide 1450 3.1 Corrode SiC
Carbon monoxide 1370 3.8 Absorb carbon powder and influence the
protection film of SiO2
Halogen 704 3.8 Corrode SiC and destroy the protection film of SiO2
Hydrogen 1290 3.1 The action on SiC produces methane and destroys
the protection film of SiO2
Nitrogen 1370 3.1 The action on SiC produces insulating layer of
silicon nitride
