· JVASP-66133· Ba4SiW

Ba4SiW is an intermetallic compound composed of barium, silicon, and tungsten, belonging to the family of refractory metal silicides. This material is primarily of research interest rather than established industrial production, with potential applications in high-temperature structural applications where tungsten's refractory properties and silicon's lightweight contribution could be leveraged.
