High Efficient Environmental Friendly Silicon Metal 2202/97 Metal Silicon For Semiconductor
What is Silicon Metal?
Silicon Metal is processed by excellent industrial silicon and including full varieties. Used in electro, metallurgy and chemical industry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.
Function
The main component silicon content is about 98%(in recent years, 99.99% of Si content is also included in metal silicon), and the remaining impurities are iron and aluminum., calcium, etc.

Applications
1.High-purity monocrystalline silicon is an important semiconductor material. Used as diode, triode, thyristor and various integrated circuit materials. It is also a promising material in energy development and can be used to manufacture solar cells, etc.
2.The ceramic and metal are mixed and sintered into a cermet composite material, which is resistant to high temperature, rich in toughness, can be cut, and integrates the advantages of metal and ceramic. It is an important material for cermet and space navigation.
3.The glass fiber with high transparency made of pure silica has high communication capacity, is free from electric and magnetic interference and has high confidentiality, and can be used for optical fiber communication.
4.Silicone organic compounds can be used as plastics and coatings and are widely used.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
