· Ho1 Ta1 Ru2

Ho1Ta1Ru2 is an intermetallic compound combining holmium, tantalum, and ruthenium in a 1:1:2 atomic ratio. This is a research-phase material studied primarily for its potential in high-temperature structural applications and advanced catalytic systems, leveraging the refractory properties of tantalum and ruthenium with the rare-earth contributions of holmium. Such ternary intermetallics remain largely experimental, with engineering adoption limited to specialized research programs exploring next-generation aerospace, chemical processing, or energy conversion technologies where conventional superalloys or refractories reach performance limits.
