Green sic 800# for semiconductor cutting

Description

• polishing green sic is produced in an electric-resistance type furnace through fusing high quality quartz sand, petroleum coke (or coal char), sawdust, salt with high temperature.
• Its hardness is between fused alumina and diamond’s.
• Higher mechanical intensity than fuse Good quality green silicon carbide 800# 22-18 for abrasive blasting d alumina’s. It is brittle and sharp and has electrical and heat conductivity in some degree.
• polishing green sic is mainly used to grinding the hard gold-bearing work piece.

Usage

1. The precise grinding of crystals and monocrystalline, hard glass.
2. It can cut the crystals, monocrystalline, polysilicon rods
3. It also be used to process the hard metal, copper and copper alloy and all kinds of resin materials.
4. polishing green sic is mainly used for processing of tungsten carbide, titanium and optical glass and grinding of cylinder liner and high-speed steel cutting tools.
5. polishing green sic micropowder is coated in inner wall of the cylinder body, improving wear resistance and prolonging 1-2 times.
6. The refractory materials made of silicon carbide have the characteristics of thermal shock resistance, small size, light weight, high strength, and energy saving effect.
