Refers to the metal powder used in refractory material, powder metallurgy industry of raw materials.
The use of metal powder
1, industrial silicon powder is widely used in refractory material, powder metallurgy industry, in order to improve the products of high temperature resistance, oxidation resistance and wear loss. Its products are widely used in steel furnace, kiln, kiln.
2, in the organic chemical industry, industrial silicon is the basic material of organic silicon polymer synthesis, such as for the production of silicon monomer, silicone oil, silicone rubber preservatives, so as to improve the product heat resistance, electrical insulation, corrosion resistance, corrosion resistance, waterproof and other characteristics.
3, industrial silicon powder made of single crystal silicon wafer processing by pulling, and is widely used in the field of high technology, integrated circuit, electronic components essential raw materials.
4, metallurgy and foundry industry, industrial silicon powder as non ferrous alloy additives, silicon steel alloy agent, so as to improve the hardenability of steel. The reducing agent of industrial silicon can also be applied to certain metal, a new type of ceramic alloy etc..
