Black Silicon Carbide – SIC

Black silicon carbide consists of crystalline silicon carbide, which is produced from silica sand and petroleum coke in electric resistance furnaces at temperatures of > 2.300 °C. Silicon carbide is iron-free, angular and extremely hard.

Applications:

Reusable abrasive
Grinding, lapping and polishing medium
Grinding wheels and grinding medium
Wear-resistant and refractory products

Blasting systems:

Pressure blast systems
Injection blast cabinets

Typical physical properties
Hardness	approx. 9 - 10 mohs
Grain shape	angular
Melting point	approx. 2300 °C
Specific gravity	approx. 3,2 g/cm³
Bulk density (depending on granular size)	approx. 1,3 – 1,5 g/cm³

Typical chemical analysis
SIC	98,00 %
Fe₂O₃	0,24 %
C-frei	0,50 %
Magnetic particles	0,12 %

Packaging
25 kg bags on pallet up to 1 ton
1 ton loose in big bag
