ceramic

· JVASP-38445· Hf2RuRh

Hf2RuRh is a refractory ceramic compound composed of hafnium, ruthenium, and rhodium, belonging to the class of high-entropy or multi-principal-element ceramics. This material is primarily of research and development interest rather than established in mainstream production, representing the emerging family of refractory transition-metal ceramics designed for extreme-temperature applications. The combination of these heavy transition metals suggests potential use in aerospace, nuclear, or ultra-high-temperature thermal management contexts where conventional ceramics reach their limits.
