Si2AsW
metal· JVASP-75873· Si2AsW
Si2AsW is a ternary intermetallic compound combining silicon, arsenic, and tungsten—a research-phase material belonging to the family of refractory metal silicides and arsenides. Limited industrial deployment exists; this composition is primarily of interest in materials science research for understanding phase stability, electronic properties, and potential high-temperature or semiconductor applications where tungsten's refractory character and arsenic's electronic doping effects may be exploited.
