Abstract:
     The method for improving physical property of wet ammonium carbonate is to add the powdered magnesium sulfate monohydrate to the wet ammonium carbonate to make its free water combine with magnesium sulfate monohydrate and change into crystal water, and make it into magnesium sulfate heptahydrate so as to make the wet ammonium carbonate become dry and smooth and have the good flowing property, so that its chemical stability is greatly raised, and the obtained product is a mixture of ammonium carbonate and a small quantity of magnesium sulfate heptahydrate.
