· JVASP-37280· SmB2Ru2

SmB₂Ru₂ is an intermetallic ceramic compound combining samarium, boron, and ruthenium, belonging to the rare-earth boride family of advanced ceramics. This material is primarily of research and developmental interest, explored for applications requiring high-temperature stability, chemical inertness, and electrical properties that differ from conventional refractories. The ruthenium component imparts unique metallic characteristics to the ceramic matrix, making it a candidate for specialized high-performance applications where conventional borides or transition-metal ceramics reach their limits.
