Ammonium sulfate is an inorganic sulfate salt obtained by reaction of sulfuric acid with two equivalents of highmelting (decomposes above 280℃) white solid which is very soluble in water ( g/100 g water at 0℃; g/100 g water at 100℃), it is widely used as a fertilizer for alkaline soils. It has a role as a fertilizer.

Ammonium sulfate is well known for the first order phase transition which occurs upon cooling to a Ferroelectric crystal. Ammonium sulfate is made by treating ammonia, often as a byproduct from cokeovens, with sulfuric acid2 . Ammonium sulfate also is manufactured from gypsum (CaSO4·2H2O).
Jun 15, 2018· Phosphogypsum (PG) as a lowcost calcium resource was used to prepare nanoCaCO 3 in a threephase system by reactions. Based on the population balance equation, nanoCaCO 3 crystal nucleation and growth model in the gas (CO 2)liquid (NH 3 ·H 2 O)solid (CaSO 4) threephase system was crystallization kinetic model of nanoCaCO 3 in CO 2NH 3 ·H 2 OCaSO 4 .

Nov 10, 2009· In extending these studies to ammonium sulfate solutions, we report the value of γ e as defined by Eq., however, p sat is the equilibrium vapor pressure of the solution, rather than that of pure water. Because this vapor pressure is ≈13% lower than that of pure water, the maximum theoretical evaporation rate for the solution is lower than that of pure water.
Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.
Ammonium sulfate preparation from phosphogypsum waste . Ammonium sulfate is a mixed fertilizer which contains nitrogen and sulfur nutrients (FAO 2003 Tisdale 2002) The ammonium sulfate provides the ideal solution that has a quick sulfate release tied in with the seasonlong availability of degradable sulfur (Hoeft et al 1985 Dudal 2002)
