· Mo5As4

Mo5As4 is a molybdenum arsenide intermetallic compound belonging to the family of metal-arsenide phases, characterized by a defined stoichiometric structure rather than a solid solution. This material is primarily of research and exploratory interest rather than established in high-volume production; molybdenum arsenides are investigated for their potential in thermoelectric applications, catalysis (particularly hydrogen evolution), and high-temperature structural applications where the combination of refractory metal properties and intermetallic strengthening could provide advantages over pure molybdenum or conventional alloys.
