· JVASP-22199· Sr5As3

Sr5As3 is an intermetallic ceramic compound combining strontium and arsenic, belonging to the family of rare-earth and alkaline-earth metal arsenides. This is a research-stage material with limited commercial production; it is studied primarily for its structural and electronic properties in solid-state chemistry and materials science contexts. The compound's potential applications lie in specialized semiconductor research, high-temperature ceramics development, and fundamental studies of metal-arsenic phase systems, though it has not achieved widespread industrial adoption compared to conventional structural or functional ceramics.
