K4Sr2SnAs4
ceramic· JVASP-140866· K4Sr2SnAs4
K4Sr2SnAs4 is an inorganic ceramic compound belonging to the quaternary arsenide family, combining potassium, strontium, tin, and arsenic in a fixed stoichiometric ratio. This material is primarily of research interest rather than established industrial production, investigated for potential applications in solid-state electronics and photovoltaic systems where mixed-metal arsenides show promise for bandgap engineering and semiconductor properties. The compound's appeal lies in its potential to offer tunable electronic characteristics through compositional variation in the arsenide family, though practical engineering adoption remains limited pending further characterization and scalability demonstration.
