Chromium(II) silicide

Chromium(II) silicide (CrSi₂) is an inorganic chemical compound consisting of chromium and silicon. It is classified as a metal silicide. It is a dark grey, refractory material, meaning it can withstand high temperatures without significant degradation.

CrSi₂ possesses a relatively high melting point and exhibits good oxidation resistance at elevated temperatures, properties that make it suitable for certain high-temperature applications. It is a semiconductor material, exhibiting semiconducting properties.

In terms of crystal structure, CrSi₂ typically adopts a hexagonal structure.

Chromium(II) silicide can be synthesized through various methods, including direct reaction of chromium and silicon at high temperatures, or through chemical vapor deposition (CVD) techniques.

Possible applications of CrSi₂ include high-temperature coatings, diffusion barriers in microelectronic devices, and as a component in thermoelectric materials. Its thermoelectric properties have been actively researched.
