· JVASP-10539· K2NaGaP2

K2NaGaP2 is a mixed-metal phosphate ceramic compound containing potassium, sodium, and gallium. This is a research-phase material belonging to the polyphosphate ceramic family, studied primarily for its structural and ionic properties rather than established commercial production. Materials in this compound class are investigated for potential applications in solid-state ionics, thermal management systems, and specialized optical or electronic applications where gallium-containing ceramics offer unique functional properties.
