Industrial grade products & COA meets GB/T 9983-2004 standard:

Chemical Formula: Na₅P₃O₁₀

Molecular Weight: 367.86 g/mol

Appearance: White crystalline or powdery solid.

Form: Typically exists as an anhydrous compound (Na₅P₃O₁₀) or a hexahydrate (Na₅P₃O₁₀*6H₂O).

Water Solubility: Highly soluble in water, with solubility increasing with temperature. At 20°C, solubility is approximately 14 g/100 mL. At 60°C, solubility is approximately 30 g/100 mL.

Other Solvent: Insoluble in organic solvents (e.g., ethanol).

Aqueous Solution pH: The pH of a 1% aqueous solution is approximately 9.5-10.5, making it alkaline.

Decomposition Temperature: Decomposes at high temperatures (around 622°C) into sodium pyrophosphate (Na₄P₂O₇) and sodium metaphosphate (NaPO₃).

Hydrate Stability: The hexahydrate tends to effloresce in dry air, losing its water of crystallization.

Property: Strong hygroscopicity; easily absorbs moisture from the air and may form clumps.

Property: STPP has strong chelating ability, forming stable soluble complexes with metal ions such as calcium, magnesium, and iron in water.

Application: This property makes it highly valuable in water treatment, detergents, and food processing.
