Silicon carbide for polishing
1.Introduction
Silicon carbide produced at high temperature in an electric resistance type furnace with quartz sand
and petroleum coke as its main raw materials. made into different grain size through crystal,
choosing, crashing, magnetic, separating, screening,washing .It is classified into black silicon
carbide and black silicon carbide . Mechanical intensity of it is higher than fused alumina .
small coefficient of expansion, brittle property and good thermal conductivity .
2.Applications
For abrasives, grinding of electronics, metallurgical additive.
For special ceramics, foam ceramics, modification of coating and plastics
For auto parts, war industry and aviation, steelmaking
For abrasive and cutting tools and Cutting disks made of SiC
For grinding, honing, water-jet cutting and sandblasting.
For grinding non-ferrous materials, rock, stone, leather, rubber, hard materials
For bonded abrasive tools, lapping and polishing ,metallurgical additive and refractory material.
