ABSTRACT:
Potassium polyphosphate polymers having ratios of P.sub.2 O.sub.5 to K.sub.2 O which make them suitable as fertilizer products are prepared by reacting potassium fluosilicate also known as potassium silicofluoride with phosphoric acid and sulfuric acid at temperatures of about 250-500.degree. C.
