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.
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.
