  • Black Silicon Carbide Grit - China

    price: contact company for price

    1.Product Description black silicon carbide grit 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

    Color after firing 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.
