· JVASP-16401· PaAs2

PaAs₂ is a compound ceramic in the phosphide-arsenide family, combining phosphorus and arsenic elements into a crystalline structure. This material falls within the broader category of III-V semiconductors and refractory compounds, which are primarily of research and development interest rather than established commercial production. PaAs₂ and related phosphoarsenide ceramics are investigated for potential applications in high-temperature electronics, optoelectronic devices, and specialized semiconductor applications where extreme thermal stability and electrical properties are required, though widespread industrial adoption remains limited compared to more mature compound semiconductors like GaAs or InP.
