Ammonium Sulfate - an overview | ScienceDirect Topics

Ammonium sulfate ( (NH4) 2 SO 4) is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer since the chemical contains 21% (w/w) nitrogen and 24% (w/w) sulfur. The chemical has also been used in flame retardant chemicals because, as a flame retardant, it increases the combustion temperature of the ...
