Product Details

1.Production Description

Silicon metal, also known as crystalline silicon or industrial silicon, its main usage is as an non-iron base alloy additives. Silicon is a non-metallic element, it is gray, metal color, hard and brittle.

Silicon metal mocropowder is widely used in refractory industry and concrete industry

2. Application.

Metal silicon is an industrial purification of elemental silicon, mainly for the production of organic silicon, preparing high-purity semiconductor materials and preparation for special-purpose alloy, etc.

a.It is produced for silicone rubber, silicone resin, silicone oil

It is used for making medical supplies, high temperature resistant gaskets, because of good elasticity, high temperature resistant,, etc. Silicon resin is used in the production of insulating paint, high-temperature paint, etc.Silicon oil is a kind of oil which viscosity is affected tinily by temperature, so it used for the production of advanced lubricant, polish, fluid spring, dielectric fluid, etc., it can also be processed into colorless transparent liquid and coated on the surface buildings as a senior waterproof.

b.Manufacturing high purity semiconductor

Nearly all modern large scale integrated circuit is made of high purity silicon metal. High purity silicon metal is the main raw material for producing optical fiber.

c.Preparation for alloy

Silicon aluminum alloy is one of the largest silicon alloy dosage. it is a kind of compound deoxidizer, which can improve the utilization rate instead of pure aluminium in the process of steelmaking deoxidizer, and it can purify liquid steel and improve the quality of steel. Silicon aluminum alloy density is small, low thermal expansion coefficient, good casting properties and the anti-wear performance, alloy casting has high against impact ability and good high density with its casting, which used the shuttle and auto parts production.
