1.High Purity Black Silicon Carbide Micron Powder for Electronic Parts
♦ The black carborundum(Black Silicon Carbide ) is of high hardness, brittleness.
♦ Chemical washed and water washed good cleanness.
♦ It has sharp knife-edge and friable character as well as good thermal conductivity and quick heat dissipation.
♦ Black silicon carbide is produced in an electric resistance furnace from quartz sand ,petroleum coke and anthracite at high temperature.
