Ammonium Sulphate
CAS No.: 7783-20-2
Molecular Formula: (NH4)2SO4
Molecular Weight:132.14
Properties:
Ammonium Sulphate has PH value is 5.5 in 0.1M solution. Density 1.769 g/cm3 (20°C). Ammonium Sulphate is hygroscopic; soluble in water; insoluble in acetone, alcohol and ether. Main active ingredients are 21% nitrogen and 24% sulfur, so it can be described as NPK 21-0-0 24S. Generally, it is a by-product from chemical (cyanuric acid, capro, acrylonitrile, sodium cyanide, monosodium glutamate-MSG, methyl methacrylate-MMA, etc.) or steel plant.
Steel Grade (also call Cokeovens Grade) is fine white powder. After processing it can be white granular or flake. Caprolactam Grade is colorless (achromatic) crystalline or yellowish crystals.

Ammonium Sulphate is one of the most common use and most typical inorganic nitrogen fertilizer. Ammonium Sulphate is the best fast release, quick acting fertilizer, which can be directly used for a variety of soil and crops. It can also be used as kinds of seed fertilizers, base fertilizer and additional fertilizer. It is particularly suitable for the soil which lack of sulfur, low chlorine tolerance crops, sulfur-philic crops.
Ammonium Sulphate is very popular in Japan, Southeast Asia, as well as northeast China where plant premium rice. It is suitable for the rice seedling, the growth of tea, grass, vegetables, and fruit trees, effectually rapid promoting the growth of grain, vegetables, fruits, grass and other plants. It has more efficiency than urea, ammonium bicarbonate, ammonium chloride, ammonium nitrate etc. Large granular Ammonium Sulphate can also serve as raw material for compound fertilizer. As feed additives, it provides the nutrients of non-protein nitrogen to ruminants. Ammonium Sulphate also used for fish culture in some areas.
