Product Description
Ammonium sulfate (IUPAC-recommended spelling; also ammonium sulphate in British English), (NH4)2SO4, is an inorganic saltwith a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur.
Mascagnite is a rare ammonium sulfate mineral (NH4)2SO4. It crystallizes in the orthorhombic system typically forming as stalactitic masses exhibiting good cleavage. It is soft (not higher than 2.5 on the Mohs Scale) and water soluble. Optical properties are variable; the purest form is transparent and colorless, but opaque gray or yellow deposits are also known.
It occurs in fumaroles, as at Mount Vesuvius and associated with coal seam fires. It was named for Italian anatomist Paolo Mascagni(1752-1815) who first described the mineral.
White or off-white granule, easily soluble in water. Aqueous solution appears acid. Insoluble in alcohol, acetone and ammonia, Easily deliquescent in the air.

Usage:-
The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In 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.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells.
It is particularly effective as an adjuvant for 2,4-D (amine),glyphosate, and glufosinate herbicides.
As a food additive, ammonium sulfate is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration. It is used as an acidity regulator in flours and breads.
Ammonium sulfate is used on a small scale in the preparation of other ammonium salts, especially ammonium persulfate.
Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate.
As a flame retardant, it lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char.
Its flame retardant efficacy can be enhanced by blending it with ammonium sulfamate.
