Sodium hexametaphosphate as a polymer, a transparent glass sheet and a white crystalline powder. Strong moisture absorption; moisture after the change stick, easy to deliquescence in the air, higher solubility in water, but dissolves slowly; aqueous acidic reflected. Easy hydrolysis or phosphate into Asia. Of certain metal ions (calcium, magnesium) has the ability to generate or insoluble complexes, it can be used to soft water, and lead, silver, barium salt can generate complex.
