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.

Recommended surface load and Influences to Surfaces of the Elements in Different Operating Temperature

 

Atmosphere	Furnace Temperature(°C)	Surface Load(W/cm2)	the 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
Sodium	1310	3.8	Corrode SiC
Silicon dioxide	1310	3.8	Corrode SiC
Oxygen	1310	3.8	SiC oxidized
Water-vapor	1090-1370	3.1-3.6	the action on SiC produces hydrate of silicon
Hydrocarbon	1370	3.1	Absorb carbon powder resulted in Hot pollution
