Green silicon carbide grit and powder for SiC ceramics

Green silicon carbide grit and powder are the advanced raw materials for SiC ceramic kiln furniture.

Silicon carbide ceramic tube is a kind of refractory kiln furniture. It plays the role of supporting and conveying ceramic bodies and products in roller firing kiln and roller drying kiln. The core component of the roller kiln. Silicon carbide rollers, ceramic rollers, silicon carbide square tubes, etc. are widely used in tunnel kilns, roller kilns, natural gas kilns, electric wire kilns, silicon carbon rod electric kilns, and other fields.
Those SiC kiln furniture are made by mixing green silicon carbide powder, carbon ink, graphite powder, and high adhesive, and are formed by infiltrating metal silicon at 1700 ℃.
Silicon carbide tube has excellent high-temperature bending strength, oxidation resistance, and long-term high-temperature use without bending and fracture. Moreover, it is superior to aluminum oxide tube in thermal shock resistance and high-temperature load resistance. Thus, the SiC ceramic roller made of green silicon carbide powder has excellent performance.
This superior performance comes from the high-temperature resistance, corrosion resistance, strong chemical stability, and high hardness of green silicon carbide materials. The specifications of green silicon carbide powder for SiC ceramic are GC F90, GC F150, GC F180, GC F240, and GC F2000.
