Green silicon carbide
Code: RWGC
Silicon carbide is a man-made material manufactured through heating silica sand and carbon to high temperatures in the Acheson furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9.25),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. 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.
