· JVASP-66631· Ba4TaNb

Ba₄TaNb is an intermetallic compound combining barium with tantalum and niobium, representing a complex metal phase from the refractory metal family. This is a research-stage material studied for its potential in high-temperature structural applications, where the combination of refractory elements offers stability in extreme thermal environments. The material's notable advantage lies in its potential to enable lighter-weight, high-performance designs in aerospace and energy sectors where conventional superalloys reach their limits, though industrial deployment remains limited pending further development of processing and manufacturing techniques.
