1600C Silicon Carbide heating elements For furnace

Silicon Carbide heating elements 1.Used for heating 2.Made of SiC 3.Excellent property Silicon Carbide heating elementsSilicon Carbide (SiC) heating elements is a non-metal electric heating element made from SiC as its main raw materials. It has some specific properties, such as low expansion coefficient, little deformation, stable chemical property, long service life, easy installation and maintenance, etc. Silicon Carbide (SiC) heating elements can be directly used in an air atmosphere without any protection atmosphere. It is extensively used in the fields of metallurgy, ceramics, glass, machinery, analysis test, semiconductor, science & research and so on.

The influence of operating temperature and surface load on the rod surface in a different atmosphere
Atmosphere	Furnace temperature(°C)	Surface load(W/cm²)	The influence on the rod
Aammonia	1290	3.8	The action on SiC produces mathene and destorys the protection film of SiO2
Carbondioxide	1450	3.1	Corrode SiC
Carbo monoxide	1370	3.8	Aabsorb carbon power and influence the protection film of SiO2
Halogen	704	3.8	Corrode SiC and destory the protection film of SiO2
Hydrogen	1290	3.1	The action on SiC produces mathene and destorys 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
Sulphur dioxide	1310	3.8	Corrode SiC
Oxygen	1310	3.8	SiC Oxidized
Water-vapour	1090-1370	3.1-3.6	The action on SiC produces hydrate of silicon
Hydrocardon	1370	3.1	Aabsorb carbon power resulted in Hot pollution
