Sodium Hexametaphosphate(SHMP)

Alias:Hexasodium metaphosphate;  Metaphosphoric acid, hexasodium salt

Molecular formula: (NaPO3)6

MW: 611.82

CAS No. : 10124-56-8

Character: Sodium hexametaphosphate of commerce is typically a mixture of polymeric metaphosphates,  of which  the hexamer is one, and is usually the compound referred to by this name .

It is more correctly termed sodium polymetaphosphate. It is prepared by melting , followed by rapid cooling. SHMP hydrolyzes in aqueous solution, particularly under acidic conditions, to sodium trimetaphosphate and sodium  orthophosphate.

Uses: SHMP is used as a and has applications  with in a wide variety of industries, including as a in which it is used under the E452i. is sometimes added to SHMP to raise the to 8.0-8.6,  which produces a number of SHMP products used for and . Also used as a dispersing agent to break down clay and other soil types. One of the lesser-known uses for sodium hexametaphosphate is as a in the making of , a ceramic technique using a fine particled slip. The sodium hexametaphosphate causes the heavy particles in the slip to drop to the bottom allowing the fine particles to be siphoned off and applied to a  green ware ceramic surface. Sodium hexametaphosphate is also a whitening ingredient included in some whitening toothpastes and mouthwashes .
