According to the structure and shape can be divided into white powder anhydride (Na5P3O10) and rectangular parallelepiped crystallization of six hydrate (Na5P3O10 · 6 h2o) anhydride Ⅰ type and Ⅱ type. Industrial sodium tripolyphosphate was actually Ⅰ and Ⅱ mixture. Type Ⅰ dissolving speed, the hydration generated six hydrate thermal effect is big, easy absorption of moisture agglomerate in atmosphere. Ⅱ type moisture absorption is slow, not easy to agglomerate. Therefore, for detergent Ⅰ type content in sodium tripolyphosphate shoulds not be too high, general control in 10 ~ 30%.
