Single Spiral Sic Heating Element
SiC heating element is one type of ceramic heating elements, which use six-party high purity green SiC powder as the main raw material. Silicon is recrystallized under 2200 ℃ high temperature to form finished materials. The using temperatures up to 1450 °C under oxidation atmosphere, and constant working life up to 2000 hours. 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.
1. Selecting high purity green SiC powder, to ensure best foundation for top quality.
2. SiC tube is extruded by 500T press machine, to ensure high density uniform through whole length.
3. Excellent resistance rate between heat zone and cold zone, to avoid over-temperature of cold zone to damage furnace body.
4. Special technology to spread a protect film on the surface of hot zone, which enhance the Antioxidant property evidently and lengthen the service life.
Note: When ordering, please indicate the following data:
Length of Hot zone (HZ)
Length of Cold zone (CZ)
Resistance (at 1050C +/-50C)
