Black Silicon Carbide for bonded abrasive 1. Used for bonded abrasive 2. 20 years experiences
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.
The typical physical properties:
Hardness: approx. 9-10 mohs
Grain shape: angular
Melting point: approx. 2300°C
Specific gravity: approx. 3.2g/cm3
Bulk density: approx. 1.3-1.5g/cm3
(depending on granular size)
Typical chemical analysis:
F.C. : 0.50%
Magnetic particles: 0.12%
Business Type: Manufacturer
