· TiAs

TiAs is an intermetallic compound combining titanium and arsenic, belonging to the class of transition metal pnictides. This material exhibits ceramic-like hardness and metallic conductivity, making it of interest primarily in research contexts for semiconductor applications, thermoelectric devices, and high-temperature structural applications. TiAs is notable among pnictide intermetallics for its potential in topological materials research and as a candidate for advanced thermal management systems where conventional metallic alloys fall short.
