· JVASP-18545· LaB2Ru3

LaB₂Ru₃ is an intermetallic ceramic compound combining lanthanum hexaboride (LaB₂) with ruthenium, belonging to the rare-earth boride family of materials. This is primarily a research and experimental material studied for its potential in high-temperature applications and electron emission properties, rather than an established commercial ceramic. The material combines the electron-emitting characteristics of lanthanum hexaboride with ruthenium's thermal stability and catalytic properties, making it of interest in specialized high-temperature and vacuum electronics contexts.
