Physicochemical Properties
Molecular weight: 611.77 g/mol
Appearance: White crystalline or powdery solid
Odor: Odorless or slightly sulphide odor
Density: 2.484 g/cm³ (25°C)
Melting point: About 616°C (decomposition)
Chemical Safety: Unrestricted goods
Solubility: Easily soluble in water (pH about 6-8); insoluble in ethanol and other organic solvents
Hydrolysis reaction: Gradually hydrolyzed in water to form orthophosphate
Complexation: Forms soluble complexes with metal ions (e.g. Ca²+, Mg²+) for softening hard water
Thermal stability: Decomposes at >600°C to form sodium phosphate and oxygen
Acid base: Aqueous solution is weakly basic and reacts with acid to form phosphate
Production Process
Sodium hexametaphosphate produced by Riel Chemical is prepared from 85% thermal phosphoric acid and 99.0% high-quality caustic soda. After third-party test by SGS, the finished product contains more than 68% phosphorus pentoxide (see COA for details).
