Si2 Ce1 Re4
semiconductor· Si2 Ce1 Re4
Si₂Ce₁Re₄ is an intermetallic compound combining silicon, cerium (rare earth), and rhenium in a fixed stoichiometric ratio. This is a research-stage material rather than a production commodity; it belongs to the family of rare-earth transition metal silicides, which are investigated for high-temperature structural applications and electronic properties. The incorporation of rhenium—a refractory metal with exceptional high-temperature strength—alongside cerium suggests potential applications in extreme thermal environments, though practical use remains limited to specialized research contexts.
