· JVASP-37621· TmTa3

TmTa3 is an intermetallic ceramic compound combining thulium (a rare-earth element) with tantalum in a 1:3 stoichiometric ratio. This material belongs to the family of rare-earth transition-metal intermetallics, which are primarily of research and experimental interest for high-temperature structural applications. TmTa3 and related compounds in this family are investigated for potential use in extreme-environment applications where conventional ceramics or superalloys reach their limits, such as aerospace propulsion systems and hypersonic vehicle components, though industrial deployment remains limited and material characterization is ongoing.
