Product Description

 

94% sodium tripolyphosphate (stpp) for Ceramics

As a chained condensation compound of phosphate soluble in water, it has two existing forms: Na5P3O10(Anhydrous) and Na5P3O10•6H2O(Crystal). The specific gravity of Na5P3O10•6H2O is 2.12, that of Na5P3O10 is 0.5-0.6, melting point for both is 622°C. Anhydrous Na5P3O10 is capable of absorbing humidity with its aqueous solution being alkalinity and will be hydrolyzed to ortho-phosphates; It can have emulsification, suspension and dispersion of mud and oil; it has strong buffering effects with PH value between 4.3-14.
