What is silicon metal grade 3303?

Silicon Metal 3303 is a relatively high-grade silicon metal. Silicon metal grade 3303 consist of silicon content 99.37%, 0.3%iron, 0.3% aluminum and 0.3% of calcium.

Properties

Silicon is a semi-metal with properties of both metals and non-metals. It contracts in its liquid state and expands as it solidifies. It has relatively high melting and boiling points. When crystallized, it forms a diamond cubic crystal structure.

Silicon Metal 3303 Application

1. Use for Al alloy product: Silicon Metal could be added in aluminium alloys, to enhance the strength of the alloy, increase its anti-oxidation and corrosion resistance, decrease its density and coefficient of thermal expansion, meliorate its casting performance, and make the alloy have high impact resistance and pressure resistance.

2. Used for cold-rolled silicon steel product: After adding silicon metal in steel, it could greatly improve the magnetic properties of steel, increase its permeability, reducing the hysteresis and eddy current losses.

3. Use for high-purity semiconductor products: Due to the high melting point of silicon, good thermal stability, large band gap, and rich in resources, with technology has been improving, integrated circuits and large-scale integrated circuits made from silicon semiconductors have been used in various fields, the demand is growing up year by year.

4. Use for organic silicon products: Silicone maintains flexibility between -700℃ and 2000℃. It can be used for high-temperature gaskets and cold insulation materials. Silicon resin is used in insulating paint. It withstands 180℃ to 2000℃ and is also applied in high-temperature coatings. Silicone oil is used in senior lubricants, polishing agents, fluid springs, and dielectric liquids. It can be processed into a colorless transparent liquid and sprayed on buildings for waterproofing. Silicon metal is widely used in the organic silicon industry. Its usage is increasing and may exceed that in the aluminum alloy industry.
