Products Description
Green silicon carbide powder, also known as green silicon carbide micro powder, refers to micron-sized silicon carbide powder that is ultra-finely crushed and graded using professional equipment (such as JZFZ equipment). It is made of petroleum coke and high-quality silica as the main raw materials, with salt added as an additive, and smelted at high temperature in a resistance furnace. Green silicon carbide powder is green in color, has a crystal structure, high hardness, strong cutting ability, stable chemical properties, and good thermal conductivity.
The Mohs hardness of green silicon carbide powder is as high as 9.2, and the Vickers microhardness is between 3000~3300kg/mm². Its hardness is second only to diamond, cubic boron nitride and boron carbide among abrasives, and higher than corundum. Green silicon carbide powder has excellent thermal conductivity, high thermal conductivity, small thermal expansion coefficient, strong thermal shock resistance, and is a high-quality refractory material. Green silicon carbide powder has stable chemical properties and has high stability to corrosive media such as acids and alkalis, and does not corrode or dissolve. The purity of high-quality green silicon carbide powder is as high as 99.9% or more, and it contains almost no impurities, which ensures its excellent physical and chemical properties. There are many methods for preparing green silicon carbide powder, the most common of which is to use silicon carbide blocks through crushing, particle shaping, pickling and impurity removal, hydraulic precision classification, natural sedimentation and high temperature drying. In addition, other methods such as electrolysis and vapor deposition can also be used.
Green silicon carbide powder is widely used in wire cutting of semiconductor materials such as single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. due to its high hardness and excellent cutting ability. It is an important engineering processing material in the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry. Green silicon carbide powder has good high temperature resistance and stability. It can be used to manufacture a layer of lining material in high melting point alloy precision casting shells, as well as other refractory materials in high temperature environments. Green silicon carbide powder can be used to make abrasive tools such as grinding wheels, oilstones, sandpaper, emery cloth, and construction grinding heads. These tools play an important role in processing and surface treatment. Green silicon carbide powder is also suitable for processing and grinding metal materials such as cylinder liners, valves, cemented carbides, titanium alloys, as well as brittle non-metallic materials such as optical glass, ceramics, crystals, electronic components, crystals, silicon, germanium, stone, agate, and high-end jewelry jade.
