· JVASP-27278· Mg2B4Ru5

Mg2B4Ru5 is an intermetallic ceramic compound combining magnesium, boron, and ruthenium. This is a research-phase material studied primarily for its potential in high-temperature structural applications and electronic devices, where the combination of light magnesium with refractory boron and noble-metal ruthenium offers an unusual balance of properties. The material family represents an emerging area in advanced ceramics, with industrial adoption limited but potential applications in aerospace, catalysis, and next-generation composites where conventional borides or ruthenium alloys fall short.
