Products Description
Silicon Metal Powder: There are many ways to make silicon metal powder from silicon block as raw material, among which the common ones are Raymond method, roller method, disc grinding method and punching method, from the principle of powdering, the first three are extrusion and crushing, and the latter is impact crushing. The technical parameters of silicon metal powder obtained by different milling methods are different in terms of microstructure, specific surface area, particle size distribution and surface oxidation, and the reactivity of silicon metal powder is naturally different.

Products Pictures
1.Silicon metal powder has a wide range of applications and is mainly used in industry. Industrial silicon powder is drawn into monocrystalline silicon, and the processed silicon wafers are widely used in high-tech fields, which are indispensable raw materials for integrated circuits and electronic components.
2.In the metallurgical casting industry, industrial silicon metal powder is used as a non-iron-based alloy additive and silicon steel alloy agent, thereby improving the hardenability of steel. Industrial silicon fume can also be used as a reducing agent for some metals, for new ceramic alloys, etc.
3.The existing silicon metal powder production method is commonly used in the production process of neutral mill. In the production process, the silicon block is dried and crushed and fed into the vertical mill, and the grinding silicon powder is brought out by the circulating air flow, collected by the collector, and the collected powder is screened by the vibrating screen, and the coarse grains on the screen are returned to the mill, and the fine grains under the sieve enter the finished product warehouse.
4.In the production process, the silicon block is dried and crushed and fed into the Raymond mill, and the grinding silica powder is brought out by the circulating air flow, and the dust is collected by the cyclone dust collector, and the collected powder is screened by the vibrating screen, and the material on the screen is returned to the Raymond mill, and the material under the screen enters the finished product warehouse.
5.Our company has its own factory to produce and has a large number of high-quality silicon metal powder. If you need, please contact us, we will have a professional team to serve you, whether it is products or services will make you satisfied.
