Description

Silicon carbide (SiC) is made from quartz sand and petroleum coke (or coal tar), wood chips as raw material through high temperature smelting in electric resistance furnace.

 Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp has electrical and heat conductivity in some degree.

Chemical composition  

silicon carbide 

1.content: SiC 50-99.5% 

2.type: sand, grit OEM

3. size: sand: No. 14-No. 240, F-grit F12-F2000, P-grit P12-P2000, OEM

4:package: 5Kg/bag, 10Kg/bag, 20Kg/bag, 25Kg/ bag,1Mt/big bag or OEM

5.application: Refractory, metallurgy, cast-on outwell, abrasive materials, functional ceramics, semiconductor fabrication, silicon carbide fiber, building materials, chemical industry and so on.  

F12-F14, use for sandblasting, rust removal, snagging, heavy duty grinding of steel ingot, leather, salt, floor boards.

F14-F30,use for casting play burr, cutting billet and steel tube, flat kibbling, steel ingot grinding, marble grinding, or as refractory material.

F30-F60, use for surface abrasion, outside & surface grinding, centerless grinding, tool grinding of quenching or no-quenching steel profiles, copper or other hard metal.

F60-F100, use for precision grinding, cutter sharpening, gear grinding, etc.

F100-F240, use for cutter sharpening, rough grinding, precision grinding, thread grinding.

F280-F600, use for precision grinding & thread grinding of instrument and matter a gear products.

F600-F2000, super-precision polishing, mirror polishing, surface lapping,etc.

P-grit, P12-P2500, used for coated abrasives products, outstanding advantages compared to F-grit is the More concentrade grit distribution of the basic grain, narrow grain span than F-grit

Advantages

1. It can reduce the cost in the production

2. It can improve the capability and quality of the finished product

3: Remove oxygen from iron compound. 

4: Adjust the carbon content, increase the silicon and elevate the temperature.

5: It can replace ferrosilicon and cast iron

6. It costs less than ferrosilicon and carbon combination. 

7. It has no dust nuisance while feeding the material. 

8. It can speed up the reaction. 

9. Corrosion resistance, high strength, high hardness. 

10. Good wear-resisting performance, resist to shock.
