Properties:Transparent glass slide or white crystalline powder. Strong moisture absorption; and become stick after the moisture absorption. Easily become damp in moist air,and easily dissolve in water. High solubility in water, but dissolved slowly; aqueous solution is acidity,easy hydrolyzed or turn into phosphate.
Applications:SHMP is used as a sequestrant and has applications with in a wide variety of industries.Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0-8.6,which produces a number of SHMP products used for water softening and detergents. 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 deflocculant in the making of terra sigillata,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.
