NaPO3

Sodium polyphosphate (NaPO3) is an inorganic ceramic compound belonging to the phosphate glass and binder family, commonly produced as a glassy or vitreous solid. It is widely used as a binder, adhesive, and glass-forming constituent in industrial ceramics, dental materials, and flame-retardant coatings, where its thermal stability and glass-transition properties enable bonding at moderate temperatures. Engineers select NaPO3-based formulations for applications requiring low-cost inorganic adhesion, corrosion resistance, and thermal processing in environments where organic polymers would degrade, though its hygroscopic nature and moisture sensitivity require careful handling in humid conditions.
