Porous SiC-Si-C ceramics were produced by reaction sintering (RS) of silicon carbide, silicon, and carbon powder compacts in the temperature range of 1400–1600 C. The effects of chemical composition of the starting powder, initial SiC particle size, and reaction sintering temperature and duration on the densifiion and microstructure of ceramic materials were studied.
Gray silicon carbide abrasives are used on hard and brittle substances, such as grey iron and cemented carbide, and low tensile strength metals, such as brass, aluminium, and copper. Green chromium (III) oxide is the abrasive used in green compounds that are typically used to finish ferrous metals (steels).
