· JVASP-41736· LiHf2Re

LiHf2Re is an experimental ternary ceramic compound combining lithium, hafnium, and rhenium. This material belongs to the class of refractory ceramics and is primarily investigated in research contexts for ultra-high-temperature applications where conventional ceramics and superalloys reach their thermal limits. Its potential lies in aerospace propulsion systems, thermal protection structures, and advanced energy conversion devices where the combination of hafnium's refractory properties and rhenium's high melting point could offer improved performance, though industrial adoption remains limited and material characterization is ongoing.
