Properties of copper silicide:
Copper silicide (Cu5Si), also known as five copper silicides, is a binary silicon compound of copper and an intermetallic compound, which means that its properties are between ionic compounds and alloys. This solid crystal material is a silver solid insoluble in water. It has excellent conductivity, thermal conductivity, ductility, corrosion resistance and wear resistance.
Use of copper silicide:
Copper silicide films can be used to passivate copper based chips, suppress their diffusion and electron migration, and serve as diffusion barriers. Copper silicide can also be used to directly synthesize organosilicon compounds in industry. In the reaction, copper silicide can silicify chloromethane. For example, an industrially useful dimethyldichlorosilane can be prepared. It can also be used in silicate electronic industry, electric vacuum devices, integrated circuits, ships, automobiles, light industry, aerospace and other scientific and technological fields.
Packaging and storage:
This product is packed in inert gas filled plastic bags, sealed and stored in a dry and cool environment. It should not be exposed to the air to prevent moisture and oxidation agglomeration, which will affect the dispersion performance and use effect
