Sodium metaphosphate (NaPO₂) is an inorganic ceramic compound belonging to the phosphate glass family, typically used in glassy or amorphous form rather than as a crystalline ceramic. It appears primarily in research and specialized industrial contexts, where its glass-forming properties and chemical stability make it valuable for applications requiring thermal durability or specific optical/chemical functionality. Compared to traditional silicate glasses, phosphate-based ceramics like NaPO₂ offer faster dissolution rates and biocompatibility advantages, making them of particular interest in biomedical research and specialized coatings.
