Reaction Bonded Sisic Silicon Carbide Beams For Industrial Furnaces High Hardness
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 1680° C, the melt silicon powder reacts to the silicon in the body, finally from β-Sic due to the heat of reaction.
Sintered-alpha silicon carbide (SSiC) components are manufactured by pressureless-sintering a shape produced by slip casting, extruding, or pressing submicron alpha-silicon carbide powder. SSiC has the highest MOR, best oxidation resistance and highest use temperature (1750°C) of the four materials under discussion. SSiC is also the most expensive of the four materials and is generally economically viable only as an alternative to ReSiC at temperatures above the 1450°C use limit of NSiC.
2. Product features
