Reaction Bonded Silicon carbide kiln product(RBSC)
Description
1.Sintering Theory
Reaction bonded SiC is made from
α-SiC powder, graphite powder,mixing additives and organic adhesive agent.The mixture body is extruded and then filled into crucible with silicon powder.Sinter in a vacuum heating furnace at 1600 ~1800° C,the melt silicon powder reacts to the silicon in the body,finally from β-SiC due to the heat of reaction.
2.Product Range&Features
We produce high quality RBSC products including beams,rollers and cooling air pipes,burner nozzles,crucibles and saggers,batts and pallets,radiation pipes,special linings,wear-resistant parts,sand-blast nozzle,special-shaped plates,thermal protection tubes,desulphurizing nozzle,and the like.
With the features of high strength,high temperature resistance, high hardness, high wear resistance, corrosion resistance, oxidation resistance,thermal shock resistance, thermal shock resistance,good thermal conductivity and thermal efficiency.Has been widely used ceramics,porcelain,magnetic materials, glass,industrial furnaces, automotive, pumps, boilers,environmental protection, paper, petroleum,metallurgy,chemical industry, machinery,aviation, aero space and other fields.Our products can replace similar imported products.
