Black silicon carbide
Code: RWC
Silicon carbide is a synethic material manufactured by silica sand and blind coal or petroleum coke under high temperatures. Silicon carbide is an extremely hard material (Mohs hardness 9.25) just lower then diamond, good thermal conductivity and electric conductivity. high thermal conductivity and low linear thermal expansion are some of the properties that make silicon carbide an outstanding material in its main areas of usage. Microcosmic shape is a hexagonal crystal,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.
Main application: solar wafer,semiconductor wafer and quartz chip wire sawing and lapping, bonded and coated abrasive tools, stone polishing, sand blasting,processing metal and non-ferrous metal with low tensile strength ,such as:gray pig iron ,brass,aluminum ,stone,leather and rubber.
