Description

Description:
 

Black Silicon Carbide is produced in electrical internal resistance furnaces from high purity silica sand and petroleum coke. Its combination of being very hard and sharp makes it a very aggressive abrasive ideal for many applications.
 

Applications:
 

Black SiC is typically used on hard or brittle materials. It is particularly used for high quality vitrified or resin bonded grinding wheel,lapping and polishing applications.
 


Typical Chemical Analysis:
   
Silicon Carbide(SiC)                   98.50%
Free Carbon ( C )   0.25%
Fe2O3   0.25%
       
     

Physical Characteristics:
 
Crystal Form:       Hexagonal (Alpha SiC)
True Density:       3.21 g/cm3
Hardness:       Knoop (100) 2500 kg/mm, Mohs 9.2
Melting Point:       SiC does not melt but dissociates
Color:       Black
