2. Info. of silicon carbide
Material:
• quartz sand
• petroleum coke
Produced in:
high temperature in an electric resistant furnace.
Its hardness is between corundum and synthetic
diamond and its mechanical strength is higher than
corundum, which makes it an ideal material for
high quality abrasive tools.

quartz sand
salt as additive
Produced in:
an electric resistant
furnace
Property:
•hexagonal crystal
•a good hardness
•strong cutting ability,
•excellent heat-
conducting

6. Black VS Green
• Material : Add the salt when producing the GC
• Sic content: 98% min for C, 99% for GC
• Color: Black for C, Green for GC
• Size : FEPA JIS W standard for GC while the FEPA, P,Sector sand, Mesh size
• Black sic contains more free silicon and carbon , not pure as green sic
• When comes to the wire sawing, the green silicon carbide is a good choice
• Unless the application requires more pure sic, the black sic is more economic
