Product Description

Powder Sodium Tripolyphosphate Na5P3O10 94% For Deregent


White powder or granular

 Na5P3O10,

Molecular weight 367.86

Melting point 622 °C

free soluble in water, aqueous solution appears acid.

 It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity. It is an inorganic compound with formula Na5P3O10, is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.

It has different bulk density, i.e. low density 0.35-0.6g/cm 3 , medium density 0.6-0.8g/cm3 and high density 0.8-1.0g/cm3. This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.
