    Black silicon carbide

    1. Details

    Black silicon carbide

    CODE: BC-BSC 

       Black ,frangible and sharp,good thermal conductivity and electric conductivity . Microcosmic shape is a hexagonal crystal ,mohs hardness is 9.3 ,microhardness is 2940-3300kg/mm2,density generally view is 3.20-3.25g/mm3 ,density of heap is 1.2-1.6g/mm3,specific gravity is 3.20-3.25. Raw material  are petroleum coke and quality silicon sand ,appended with salt ,then smelt in electric arc furnace. 

       Main application: solar wafer,semiconductor wafer and quartz chip wire sawing and lapping;bonded and coated abrasive tools:stone polishing;processing metal and non-ferrous metal with low tensile strength ,such as:gray pig iron ,brass,aluminum ,stone,leather and rubber.
