TmAs3

TmAs3 is a rare-earth arsenide ceramic compound combining thulium (a lanthanide) with arsenic in a 1:3 stoichiometric ratio. This is primarily a research material studied for its electronic and thermal properties within the rare-earth pnictide family, rather than a widely commercialized engineering ceramic. The material is of interest in solid-state physics and materials research for potential applications in thermoelectric devices, semiconductor research, and high-temperature material studies, though it remains largely in the experimental phase with limited industrial deployment compared to established ceramics or semiconductors.
