Silicon carbide heating elements compared with metal electric heating element, with the use of high temperature (1500 degree), oxidation resistance, corrosion resistance, long life, micro deformation, easy installation and maintenance, etc. Silicon carbide products are thick end, such as silicon carbon rod diameter, type have straight type rod, u-shaped rods, three-phase rods, gun rods, five section bar, channel bar, single threaded rods, double screw rod, various specifications of the silicon carbon rod diameter range for 8 - Φ Φ 54 mm. High silicon carbide surface infrared radiation rate high temperature can reach 1500 degrees, 5 to 10 times that of ordinary nichrome wire, high mechanical strength, bending strength is as high as 100-120 mpa, the oxidation resistance is strong, strong corrosion resistance, and has excellent heat resistance, impact resistance long service life, simple installation and maintenance. Silicon carbon rod model: model: GD (diameter) when ordering, please let us know the following data: OD: diameter; HZ: length of hot end; CZ: cold end length; OL: overall length. If you have special request for resistance, please let us know resistance value. The quantity of product specifications are not limited, in the process of transportation caused by broken rod by us responsible for replacement.

Chemical properties of elements
1.Antioxidant properties of elements
  The element start to being oxidized when heat to 8000C in air,and a SiO2 protect film will be generated on the surface of hot zone when temperature get to 1000-1300C,cristobalite will be crystallized at 1300C,the protect film get to a certain thickness when the  temperature get to 1500C ,which make the oxidation speed being very slowly to stable. If continue to heat to over 1627C,the potect film will be damaged and oxidation speed will be more
 rapid evidently and make the element damaged earlier.
  Though the element will be oxidized very slowly in course of application, it also will make the resistance increased following long time application,this phenomenon calls aging.In order to lower the aging speed, we use special technology to coat a protect film on the surface of hot zone in the corse of property of element evidently and lengthen the service life.
2.The effects of alkali and alkaline metal oxide to eements
  The alkali alkaline metal oxide will react with Sic at about 1300 and generate silicate, which calls alkali-chemical corrosion, and can  influence the glowing of element evidently.
3.The effects to elements from melting metal
  Some metals, such as cobalt, nickel, chrome and so  on, can corrade the element in high
 temperature melting state and affect the service life of element.

The distance between the element and the furnace wall and the object to be heated:

Application:
It is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magnet, ceramics, powder metallurgy, glass metallurgy and machinery etc. 
With SiC heating elements equipped with automated power supply system, not only can high accurate stable temperature be gained, but temperature can be adjusted by a curve automatically according to the act working condition. Thus SiC heating elements have been widely applied in the fields of national defense, machinery, metallurgy, light chemical, ceramics, semiconductors, laboratory analysis, scientific research, etc. It has become ideal heating elements of all kinds of electric kiln furnace, such as, tunel kiln, roller kiln, glass furnace, vacuum furnace, muffle furnace, smelting furnace, etc.
