Abstract

570,267. Manures. ETTLE, G. W., and IMPERIAL - CHEMICAL INDUSTRIES Ltd July 21, 1943, No. 11843. [Class 111] [Also in Group III] Ammonium nitrate for use as a fertilizer is rendered free flowing and substantially iioncaking by mixing with it powdered calcined gypsum (i.e., calcium sulphate hemihydrate, soluble anhydrite, and any intermediate hydrated calcium sulphate) or accelerated anhydrons calcium sulphate plaster, in which sulphates or acid sulphates of alkali metals or ammonium, cupric, zinc, ferrous, ferric or aluminium sulphates or their double sulphates are used as accelerators of hydration, as described in Specifications 236,695, 317,672 [both in Class 22], 459,134; and 554,952, [both in Group V]. Preferably 2-10 per cent. of plaster of.,'Paris or soluble anhydrite is used and the mixing is sufficiently intimate to form a coating on the surface of the particles-of ammonium nitrate.
