ABSTRACT:
There is disclosed a process for preparing mixed alkali metal salts of tripolyphosphate. A solution of mixed orthophosphate salts, such as sodium and potassium is dried by spraying the mixture onto a hot tumbling bed of a mixture of phosphate salts. The dried salts are then calcined at a temperature in the range of from about 350.degree. C. to about 600.degree. C., preferably above 500.degree. C. to form the mixed alkali metal salt of tripolyphosphate.
