Black Carborundum For Abrasives Paper And Grinding Wheel - China

price: contact company for price

1.Product Description black carborundum is the hardest blasting media

available. High-quality silicon carbide media is manufactured to a

blocky grain shape that splinters. The resulting silicon carbide

abrasives have sharp edges for blasting. Silicon carbide has a very

fast cutting speed and can be recycled and reused many more times than

sand. The hardness of silicon carbide allows for much shorter blast

times relative to softer blast media.

2.Chemical & Physical Properties

Crystal Form, Alpha SiC hexagonal system

Chemical nature, Slight acid

Reaction with acids, Very slight surface action with hydrofluoric acid

Reaction with Alkalis, Attacked at high temperature by alkalis and iron oxide

Oxidation-reduction effects , Starts to oxide slowly at 800oC. No reduction

True Density (g/cm3) 3.20

Hardness Knoop(kg/cm2) 2200-2500

Moh's 9.5

Color Black

Decomposition point 2200 Degrees Celsius

Grit sizes

SiC content=99.00%

F.C content=0.30%

Fe2O3 content=0.30%

3. Advantages

1. Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.

2. Good hardness, longer life.

3. Chemical washed and water washed, good cleanness.

4. Special treated products get higher purity, better toughness, and better grinding effect.
