Production of suspension fertilizers from orthophorphoric acid

摘要: An improved process for the production of concentrated, high-grade, nitrogen-phosphate (N--P2 O5) base suspension fertilizer from wet-process or other phosphoric acids and ammonia. The involves addition small proportions fluosilicic acid during preparation to cause modification monoammonium phosphate crystals shapes sizes that do not settle vibration such as occurs shipment.
