Calcium gallium oxide (CaGa₂O₄) is an inorganic ceramic compound belonging to the family of mixed metal oxides, combining alkaline-earth and post-transition metal elements. This is primarily a research and development material rather than an established commercial ceramic, investigated for potential optoelectronic and semiconductor applications where gallium-containing ceramics offer wide bandgap properties. The material is of interest to researchers exploring alternative substrates and functional ceramics for high-temperature electronics, photonic devices, and specialized optical components where conventional oxides reach performance limits.
