ZhenAn Metal Silicon Powder Manufacturer introduces what are the main components of metal silicon powder?
The main component of metal silicon powder is crystalline silicon. At first, it is in small pieces, and relatively speaking, the color is relatively stable. After a series of crushing or grinding, it is in powder form. Generally, it is inactive.
In general, the differences between metal silicon powder and silicon powder shared by metal silicon powder manufacturers are as follows. No matter which product is a product of the times in metal silicon production, it is necessary to produce clearer metal silicon powder. In metal silicon production, basic purification operations should also be done well, so as to reduce the residue components on the product.
