· Be2Re

Be2Re is an intermetallic ceramic compound combining beryllium and rhenium, representing a materials research composition rather than a commercialized engineering ceramic. This compound belongs to the family of refractory intermetallics and is primarily of academic interest, explored for potential applications demanding extreme hardness, thermal stability, and resistance to oxidation at elevated temperatures. Its high density and stiffness characteristics position it as a candidate for specialized high-performance applications, though practical engineering use remains limited due to beryllium's toxicity concerns, rhenium's cost, and the material's brittleness—challenges that drive ongoing research into processing and composite strategies to unlock its potential in demanding aerospace and defense environments.
