· Na2 Ca2 P6 O18

Na₂Ca₂P₆O₁₈ is a polyphosphate ceramic compound belonging to the family of phosphate-based ceramics, specifically a mixed sodium-calcium polyphosphate. This material is primarily of research interest for biomedical and environmental applications, as polyphosphate ceramics are known for their biocompatibility, biodegradability, and ion-exchange properties; the calcium-sodium composition makes it a candidate for bone-mimetic materials and waste immobilization systems rather than a standard structural ceramic.
