· JVASP-93821· As2W

As₂W is an intermetallic compound combining arsenic and tungsten, belonging to the family of refractory metal arsenides. This material is primarily of research and specialized industrial interest rather than a commodity engineering metal, valued for its potential in high-temperature applications and electronic/photonic devices where tungsten's thermal stability can be leveraged in conjunction with arsenic's semiconducting properties.
