LuB2Ru3

LuB₂Ru₃ is an experimental intermetallic ceramic compound combining lutetium boride with ruthenium, belonging to the family of refractory metal borides. This material is primarily of research interest for extreme-environment applications where conventional ceramics and superalloys reach their performance limits, such as hypersonic vehicle structures, nuclear reactor components, and ultra-high-temperature thermal barriers. Its appeal lies in the theoretical combination of boride hardness and refractory properties with ruthenium's high-temperature strength and oxidation resistance—properties difficult to achieve simultaneously in single-phase materials—though industrial adoption remains limited pending further development of processing methods and long-term performance validation.
