Metal silicon is also called industrial silicon or crystalline silicon. Its color issilver gray or dark gray with metallic luster. It has high melting point, good heat resistance, high resistivity andhigh oxidation resistance. Metal silicon is an excellent antioxidant, which is widely used in refractory materials and powder metallurgy industries. In order to improve the density and prevent the penetration of slag iron, the silicon metal which adding to the refractory materials can firstreact with oxygen to form a newore sealed pore. So that it canthe enhance the product’s high temperature resistance, wear resistance and oxidation resistance. Therefore, it is widely used in refractory materials such as steelmaking furnaces, kilns, and kiln furniture. In metallurgical casting industry, metal silicon is used as non-ferrous alloy additive and silicon steel alloying agent to improve the hardenability of steel. Metal silicon can also be used as a reducing agent forsome metals andas a new ceramic alloy.
We can provide various specifications of metal silicon blocks, particles and powders according to customers’ requirements.
