Silicon metal, also known as crystalline silicon or industrial silicon, contains around 98% of the main component silicon, and is mainly used as reducing agent in a variety of metal smelting.
Silicon powder is widely used in refractories and powder metallurgy to improve high temperature, wear resistance and oxidation resistance.Its products are widely used in steel furnaces, kilns and kiln furniture.In the metallurgical casting industry, industrial silicon powder is used as non-ferrous alloy additive and silicon steel alloy agent to improve the hardenability of steel.Industrial silicon powder can also be used as a reducing agent for some metals, such as new ceramic alloys.

1. Silicon metal can replace pure aluminum in steelmaking and is used as a reducing agent in many metal smelting processes.
2. Silicon metal can be used as an additive in aluminum alloy industry.Silicon can improve the fluidity and toughness of aluminum and its alloy, and has good pouring property, hardness and strength.
3. Silicon metal is widely used in refractories and power metallurgy to improve heat resistance, wear resistance and oxidation resistance.
4. In the production line of metallurgy and casting, industrial silicon powder is considered as the ferro-alloy additive, the alloy medicine of silicon steel, thus improving the hardenability of steel.
