Product Introduction of Copper Silicide Powder Cu5Si


Copper silicide (Cu5Si), also called pentacopper silicide, is a binary compund of silicon with copper.

It is an intermatallic compound, meaning that it has properties intermediate between an ionic  compound  and an alloy.

This a solid crystalline material is a silvery solid that is insoluble in water.

It forms upon heating mixtures of copper and silicon.


Application of Copper Silicide Powder Cu5Si
Copper Silicide thin film is used for passivation  of copper-based chips , where it serves to suppress diffusion and electromigration and serves as a diffusion barrier.

Copper silicides are invoked in the direct process , the industrial route to organosilicon compounds . In this process, copper, in the form of its silicide, catalyses the addition of methyl chloride to silicon. An illustrative reaction affords the industrially useful dimethyldichlorosilane.
