Product Description
Silicon metal is very rich in the earth's crust, rank only second to oxygen. Silicon metal can be divided into many kinds, including ferro silicon ,simn etc.Its main element is si whose content is about 98% and its impurities is Al, Fe, Ca etc. The additional product of silicon metal includes silica fume, edge leather, black silicon etc.Silica fume is widely used in the fireproofing and concrete industry
ce:Dark gray

Application and use:
1. Used in aluminum: An additive to aluminum alloys, silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly.
2. Used in organic chemicals: Silicon metal is used in manufacturing a number of sorts of silicones, resins, and lubricants.
3. Used in electronic parts: Silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
