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 1680° C, the melt silicon powder reacts to the silicon in the body,

finally from β-Sic due to the heat of reaction.

Product features

With the features of high strength,high temperature resistance, high hardness,high wear resistance,

corrosion resistance, oxidation resistance,thermal shock resistance, good thermal conductivity and

thermal efficiency.
