Production technology of green silicon carbide

- Nov 27, 2018-

Green Silicon carbide manufacturing method with black silicon carbide, but the use of raw materials purity requirements, but also in the resistance furnace 2200°c around the high temperature formation, green, translucent, six square crystal shape, its sic content is higher than black, physical properties and black silicon carbide similar, but the performance is slightly more than black for brittle,

It also has good thermal conductivity and semiconductor properties. According to the shape can be divided into flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup-shaped grinding wheel, disc grinding wheel, etc., according to the binder can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel and so on. The characteristic parameters of grinding wheel mainly have abrasive, viscosity, hardness, binder, shape, size and so on. Since the grinding wheel usually works at high speed, a rotary test should be carried out before use (to ensure that the grinding wheel does not break at the highest operating speed) and the static balance test (to prevent the vibration of the machine while working). After working for a period of time, the grinding wheel should be trimmed to restore grinding performance and correct geometry.
