· JVASP-25500· LuB2Ru

LuB₂Ru is an advanced ceramic compound combining lutetium diboride with ruthenium, belonging to the rare-earth boride family of materials. This is a research-phase material primarily investigated for extreme environment applications where exceptional hardness, high-temperature stability, and metallic conductivity are required simultaneously. While not yet widely commercialized, materials in this class show promise as alternatives to conventional refractory ceramics and hardmetals in specialized aerospace and industrial applications.
