1. Product Introduction
Sodium hexametaphosphate (SHMP) is an inorganic compound. Its chemical formula is (NaPO3) 6. Sodium hexametaphosphate is a white crystalline powder. It is easily soluble in water and insoluble in organic solvents. Sodium hexametaphosphate is mainly used in the food industry as a quality improver, pH regulator, metal ion chelating agent, adhesive, and expanding agent. It is widely used in sauces, meat products, all kinds of drinks, etc. For industrial use, such as oil field, paper-making, textile, dyeing, petrochemical industry, tanning industry, metallurgical industry and building material industry, sodium hexametaphosphate (SHMP) is mainly used as a water softening agent in solution for printing, dyeing, and boiler.It also can be used in ceramics, glaze and enamel industry.

3. Product Applications
4. Functions in glaze and enamels
2. Improve glaze viscosity Adding an appropriate amount of sodium hexametaphosphate to the glaze can increase its viscosity, making it less prone to loss during firing, maintaining the thickness and glossiness of the glaze layer, and making the surface of the ceramic smoother and more beautiful.
3. Reduce glaze tension
