Silicon Carbide is a high quality lapping abrasive available in two types viz. Black & Green. Its hardness is next to boron carbide which permits ultra precision lapping of hard & soft materials. Black silicon carbide is most suitable for lapping of brittle materials to materials having low tensile strength.
