Ga2Si3

Ga2Si3 is an inorganic compound consisting of gallium and silicon in a 2:3 ratio. It is categorized as a gallium silicide, an intermetallic phase in the Ga–Si binary system.

Formation and structure: The compound has been reported in phase equilibrium and crystallographic studies of the Ga–Si system. Its exact crystal structure can vary between reports and sample histories; some investigations assign it to a particular low-symmetry arrangement characteristic of intermetallics in this system.

Synthesis: Ga2Si3 can be prepared by direct synthesis from elemental Ga and Si at elevated temperatures in an inert or evacuated environment, followed by controlled cooling to promote the formation of the Ga2Si3 phase.

Properties and applications: As with other gallium silicides, Ga2Si3 is primarily of interest to researchers in solid-state chemistry and materials science. Reported properties are not widely standardized and depend on phase purity and preparation method. The material has limited oxidation resistance and is typically studied for fundamental aspects rather than commercial applications.
