Na4P2O7
ceramic· 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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
