Na4P2O7

Sodium pyrophosphate (Na₄P₂O₇) is an inorganic ceramic compound belonging to the phosphate glass and salt family, commonly produced as an anhydrous powder or vitreous form. It is widely used in detergent formulations, food processing, metal treatment, and ceramic manufacturing, where it functions as a dispersant, builder, and fluxing agent; its alkaline nature and water-solubility make it valuable for applications requiring controlled phosphate chemistry and thermal stability, particularly where traditional phosphate glasses or sodium phosphates are preferred for their processing ease and cost-effectiveness.
