Sodium tripolyphosphate is an inorganic substance with the chemical formula Na5P3O10. It is a kind of amorphous water-soluble linear polyphosphate. Sodium tripolyphosphate has two crystalline states: type I (high-temperature type) and type II (low-temperature type). The difference lies in their different bond lengths and bond angles. Their chemical properties are the same, but the thermal stability and hygroscopicity of type I are higher than that of type II.
