· JVASP-106192· SrMg2As2

SrMg₂As₂ is an intermetallic ceramic compound combining strontium, magnesium, and arsenic in a defined stoichiometric structure. This material belongs to the family of ternary pnictide ceramics and is primarily investigated in solid-state physics and materials research rather than established industrial production. The compound is of interest for semiconductor and thermoelectric applications due to its crystalline structure, though it remains largely experimental; potential development pathways include use as a wide-bandgap semiconductor, thermoelectric component in high-temperature energy conversion, or functional ceramic in niche electronic device applications.
