BaHfZr4
metal· JVASP-69221· BaHfZr4
BaHfZr₄ is a barium-hafnium-zirconium intermetallic compound belonging to the refractory metal family, designed for extreme-temperature and high-strength applications. This material is primarily investigated in aerospace and nuclear research contexts for its potential in thermal barrier coatings, high-temperature structural components, and advanced reactor materials where conventional superalloys reach their limits. Its combination of refractory elements makes it notable for thermal stability and resistance to oxidation, though it remains largely experimental and not widely commercialized in mainstream engineering applications.
