nature : Na5P3O10. Commonly known as sodium tripolyphosphate. A stable type I and type II meeting of stability. The white crystalline powder or crystal. Chain into the molecular structure. Six water from a hygroscopicity. Water-soluble, aqueous solution was weakly alkaline hydrolysis gradually generation sodium ions, ion pyrophosphate and phosphate ions. Heat to 622 ° C melt produce sodium pyrophosphate. For meat processing, synthetic detergent formulations (with synergies), textile dyeing, is also used as a dispersant, cosolvent so. From member of sodium dihydrogen phosphate molecules and two Na2HPO4 fully mixed, heated to 110 ° C dehydration, continue to 540-580 ° C heat derived type I dehydration. Another heated to above 620 ° C melt, reduce temperature to 550 ° C in air cooling, that is disintegrating into a powder-like type II. Anhydrous in the aqueous solution by adding ethanol, availability of water from six.
