INTRODUCE

The processing of metal silicon powder refers to the process of crushing the silicon block (25~80mm) smelted by special process to produce the specified particle size (usually 80~400 μ π ι) Range of silica fume processes. The metal silicon powder used for the production of organic silicon and polycrystalline silicon must have corresponding technical indicators. The key technical indicators of the metal silicon powder: chemical composition, particle size, morphology, specific surface area, and physical and chemical properties reflect the chemical reactivity of the metal silicon powder. The key technical indicators are an important basis for preparing organic silicon and polycrystalline silicon with high quality.
