· JVASP-106806· HfUNb2C4

HfUNb2C4 is an experimental refractory carbide compound containing hafnium, uranium, and niobium, representing a research-phase material in the ultra-high-temperature carbide family. This material belongs to a class of complex metal carbides being investigated for extreme thermal environments where conventional superalloys and ceramics reach their limits. Interest in this composition stems from the potential to combine the refractory properties of hafnium and niobium carbides with uranium's density and thermal characteristics, though practical applications remain largely in the research domain.
