· JVASP-37692· YbB4Ru

YbB4Ru is a rare-earth boride ceramic compound combining ytterbium, boron, and ruthenium. This material is primarily a research-phase compound studied for its potential as a high-temperature structural ceramic and electronic material, belonging to the hexaboride family known for exceptional hardness and refractory properties. The specific incorporation of ruthenium suggests investigation into enhanced thermal conductivity or electronic functionality compared to simpler boride ceramics, making it of interest in advanced materials research rather than established industrial production.
