Silicon Carbide Abrasive

Details
Silicon carbide is a super-hard material produced by smelting silicon dioxide and anthracite or petroleum coke in a smelting furnace at a high temperature of 1800-2500 degrees and after 50-200 hours. The hardness reaches 9.3-9.5 (Mohs hardness is 10 at the highest). It has the advantages of wear resistance, high hardness, high temperature resistance, small expansion coefficient, and oxidation resistance.


The silicon carbide raw materials can be divided into black silicon carbide and green silicon carbide due to different smelting raw materials.

Internationally, the codes for black silicon carbide and green silicon carbide are: C, GC.

The specifications of silicon carbide are internationally divided into European standards: FEPA standards, which are abbreviated as F. Japanese standard: JIS standard.

The European (FEPA) standards are: F4 #, F5 #, F6 #, F7 #, F8 #, F10 #, F12 #, F14 #, F16 #, F20 #, F22 #, F24 #, F30 #, F36 #, F40 #, F46 #, F54 #, F60 #, F70 #, F80 #, F90 #, F100 #, F120 #, F150 #, F180 #, F220 #, F240 #, F280 #, F360 #, F400 #, F500 # , F600 #, F800 #, F1000 #, F1200 #, etc.

Japan (JIS) standards are: JIS # 240, JIS # 280, JIS # 320, JIS # 360, JIS # 400, JIS # 500, JIS # 600, JIS # 700, JIS # 800, JIS # 1000, JIS # 1200, JIS # 1500, JIS # 2000, JIS # 2500, JIS # 3000, JIS # 4000, JIS # 6000, JIS # 8000, etc.

Silicon carbide is used in the field of abrasives: Because silicon carbide is higher in hardness than general metals and ceramics, it is mainly used in polishing, grinding, cutting, and sandblasting processes. It has the advantages of high grinding efficiency, obvious polishing effect and fast cutting speed. Materials such as metals, gems, polysilicon, glass, ceramics can be processed and processed.
