Main uses of Si Metal Powder

Main uses of metal silicon powder
(1) In the refractory industry, metal silicon powder is mainly used for carbon-containing materials to improve the wear resistance and oxidation resistance of products. In the powder metallurgy industry, metal silicon powder can be used as an additive.
(2) Used in organic silicon high-density synthetic materials, production of silicon monomers, silicone rubber preservatives, silicone oil, etc. It cannot be separated from metal silicon powder. Metal silicon powder occupies an important position in organic silicon chemical industry. It can improve various properties of products, such as high temperature resistance and corrosion resistance.
(3) High-tech fields cannot do without metal silicon powder. Metal silicon powder is processed into single crystal silicon and further made into silicon wafers. It is an important material for making electronic components and integrated circuits.
(4) Silicon powder is mainly used as an additive, alloying agent and reducing agent in the metallurgical industry to change the composition of steel and optimize the properties of steel, such as aluminum-silicon alloy, ferrosilicon alloy, copper-silicon alloy, etc.
