· JVASP-56714· KNiP3O9

KNiP₃O₉ is a phosphate-based ceramic compound containing potassium, nickel, and phosphorus oxide in a crystalline structure. This material belongs to the family of transition metal phosphates, which are primarily of research and development interest for applications requiring specific ionic conductivity, catalytic, or structural properties. While not yet widely established in mainstream industrial production, phosphate ceramics of this type show promise in energy storage systems, catalytic applications, and specialized refractory contexts where nickel's electrochemical properties can be leveraged.
