    Black silicon carbide



    Product Description

    Black silicon carbide also called black carborundum. This product, chemical formula of which is SiC, is obtained from the synthesis of high purity quarts sand and petroleum coke as basic raw materials under high temperature in an electric resistance furnace. It contains 85-99% of SiC and the admixtures of Fe2O3, Al2O3, CaO, SiO2, MnO2.
    It is characterized by great hardness (9,2 in Mohs scale) and micro hardness (circa 2940- 3320 kG/mm2). Its specific gravity (density) of hexagonal type, which is affected by the degree of impurity, comes to 3,20+/-0,05 g/cm3. Bulk density equals 1,20 – 1,60g/cm3. Good thermal conductivity, low thermal expansion (decreasing with temperature growth) and high strength are another characteristics that ensure a wide use of the material. Electrically it is a semiconductor. Compared with green silicon carbide, the purity, hardness and brittleness of black SiC are lower

    Application


    Black silicon carbide (SiC ) is typically used on hard or brittle materials.

    It is also used for:

    • kiln furniture
    • lapping and polishing
    • non-woven
    • tumbling
    • pressure blasting
    • anti-skid
    • electrical heating elements
    • aerospace
    • composites
    • Reusable abrasive
    • Grinding, lapping and polishing
    • Wear-resistant and refractory
    • Grinding wheels

    Advantage


    • having sharp knife-edge..
    • electrical conductivity, thermal conductivity
    • high working efficiency
    • Highly friable abrasive media which is reusable but less durable than brown aluminum oxide
    • Cleaning or etching the hardest sub-surfaces
    • Used for grinding, lapping, and wire saw cutting as well as abrasive blasting


    Packing



    1.25kg PP bag,40 woven bags/jumbo bag/pallet


    2.25kg paper bag,40 paper bags/pallet
