Silicon carbide grains are sharper and harder than aluminum oxide grains, but silicon carbide is less durable than aluminum oxide. Silicon carbide is best for non-metallic or low tensile strength materials, while aluminum oxide works best on materials with high tensile strengths. Both can be combined to produce a finer, smoother abrasive cut ...

Nov 13, 2000· Sintered alpha silicon carbide (SiC) is produced by initially mixing fine (sub-micron) and pure silicon carbide powder with non-oxide sintering aids. The powdered material is formed or compacted by using most of the conventional ceramic forming processes such as die pressing, isostatic pressing and injection moulding.

Sintering is a heat treatment applied to a powder compact in order to impart strength and integrity. The temperature used for sintering is below the melting point of the major constituent of the Powder Metallurgy material. After compaction, neighbouring powder particles are held together by cold welds, which give the compact sufficient "green ...
