Ho4 Ge4 Ir4

Ho₄Ge₄Ir₄ is an intermetallic ceramic compound combining holmium (a rare-earth element), germanium, and iridium in a 1:1:1 stoichiometric ratio. This is a specialized research material rather than a mainstream engineering ceramic, belonging to the family of rare-earth intermetallics that are studied for their potential high-temperature stability and unusual electronic or magnetic properties. The compound would be of interest primarily in advanced materials research contexts where combinations of rare-earth elements with transition metals and semiconducting elements are explored for novel functional properties at extreme conditions.
