· Na3PO4

Sodium phosphate (Na₃PO₄) is an inorganic ceramic compound commonly encountered as a white crystalline solid in powder or granular form. It functions primarily as a chemical reagent and processing aid rather than as a structural material, valued for its solubility, ionic conductivity, and role in chemical reactions across multiple industrial sectors. The material is widely used in water treatment, detergent formulations, food processing, metal surface treatment, and ceramic processing, where its alkalinity and phosphate chemistry enable descaling, pH adjustment, and binding applications; engineers select it when compatibility with aqueous systems and mild alkaline conditions is required, though it is not suitable for load-bearing or high-temperature structural applications.

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.
