ceramic

· JVASP-36451· Sr3AsP

Sr3AsP is a ternary ceramic compound composed of strontium, arsenic, and phosphorus, belonging to the class of intermetallic ceramics or ceramic phosphides. This material is primarily of research interest rather than established industrial production, studied for its potential in semiconductor, optoelectronic, and thermal management applications due to its ionic-covalent bonding characteristics. The Sr3AsP family represents an emerging material class for exploring novel electronic properties and thermomechanical performance in niche applications where conventional ceramics or semiconductors are insufficient.
