PROCESS FOR DISPERSING SOLID MATERIALS A B B T R A C T PolyphosPhate salt mixtures which have been obtained by the neutralization of a polyphosphate acid comprising from 82 to 86% by weight of P2O5 with a basic derivative of sodium or a mixture thereof with potassium have been found to be especially useful as dispersing agents for particulate inorganic solids in aqueous media. They are especially effective when used to disperse certain types of clay. The partially neutralized sodium salts of such polyphosphoric acids are surprisingly soluble in aqueous solution and the dispersants are preferably manufactured and transported in the form of such solutions.
