· JVASP-75635· HfMoAs

HfMoAs is a ternary intermetallic compound composed of hafnium, molybdenum, and arsenic, representing a specialized class of refractory metal arsenides. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in high-temperature electronics, thermoelectric devices, and advanced structural applications where extreme thermal stability and chemical resistance are required. The combination of hafnium's refractory properties with molybdenum's strength and arsenic's semiconducting characteristics makes this compound notable for exploring novel performance in extreme environments where conventional alloys degrade.
