Metal silicon powder and silicon powder are different products

Metal silicon powder and silicon powder are different products, and there is an essential difference between the two
Uses of metal silicon powder: Metal silicon powder: It is a powdered silicon powder made of metal silicon (industrial silicon) by grinding materials.
Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive in non-ferrous alloys. Industrial silicon is also used as an alloying agent for silicon steel with demanding working requirements, a deoxidizer for special steel grades and non-ferrous metal alloys in smelting enterprises. After a series of processing, industrial silicon can be absorbed into single crystal silicon wafers in the electronics industry.
