Choosing the Right Blast Media for Abrasive Blasting

Coal slag is by-product of coal-burning power plants, considered a “green” abrasive because it would otherwise be disposed of as waste. It is a relatively cheap, low dusting abrasive with low free silica, but is considered a dirty abrasive and not widely used in wet abrasive blasting because the high amount of “fines” (fine particles

Black /Green Silicon Carbide

Silicon carbide is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) in a resistance furnace. At present, silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 3.20-3.25 and a microhardness

Silicon Carbide (SiC): The Future of Power? | Arrow

Silicon carbide, also known as carborundum /kɑːrbəˈrʌndəm/, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions requiring high endurance, …
