Uses of Silicon powder

（1）High purity monocrystalline silicon is an important semiconductor material.A silico-organic compound with excellent properties that can be used to make semiconductor devices and integrated circuits.It can also be used in the form of alloys (such as ferrosilicon alloys) for automotive and mechanical parts.Also used with ceramic materials in cermet.It can also be used to make glass,concrete,brick,refractory materials,siloxane,silane.Making silane and silicone.Manufacturing silicon organic compounds,alloys,refractories, etc.

（2）The ceramic and metal mixed sintering, made of cermet composite material,high temperature resistance,toughness,can be cut,set the advantages of metal and ceramic.Glass fiber with high transparency made of pure silica,optical fiber communication capacity is high,and is free from electrical and magnetic interference,and has a high degree of confidentiality,silicone organic compounds can be used as plastics,coatings,etc.has been widely used.

Product advantage

At present,the factory can produce nano level,sub-micron level,micron level and other different particle size products.Already realized industrial production of products can be provided by tonnage level,other granularity can be accepted by customers.According to the microscopic morphology of silicon powder,silicon powder (like sheet),silicon powder (spherical);The product contains a large granularity distribution span;The packing specifications can be customized according to the customer's feeding quantity.
