- In many sources, the name “sodium hexametaphosphate” is used for mixtures of sodium polyphosphates rather than a single well-defined compound. In such cases, especially in industrial applications (e.g. detergents and water treatment), the material may correspond to Graham’s salt (Q72507913) or related sodium polyphosphate mixtures rather than a pure cyclic hexametaphosphate.
