Sodium Hexametaphosphate, Grade : Technical Grade

As a sort of sodium henamephophate polymers, it is transparent glass disk or white powder crystal. It has a very strong capability of moisture absorption and becomes viscous after moisture absorption. It is easy to be moist in the air. It is water-soluble with a large solubility in the water but a low dissolution speed. Its water solution assumes the acid reaction. It is easy to be hydrolyzed into phosphite. With the capability to create soluble complexes for some metal ions (calcium, magnesium), it can be applied to soften the water. It can also create complexes with lead, argentum and barium salts.
