Ammonium sulphate

CAS No: 7783-20-2     

EINECS No.: 231-984-1

Molecular formula: (NH4)2SO4

Purity: 99% min

Nitrogen content: 20.5% min

Appearance:  White crystal /granular

Features:Industrial ammonium sulphate is white or light grey crystal. It is hydroscopic,and apt to dissolve in water(not in alcohol or acetone),and it will become solid blocks when absorbing moisture. The aqueous solution is alkalinous. It reacts with alkali to release ammonia gas.

Applications:

1.In agriculture, used for nitrogen fertilizer. It is a kind of action fertilizer,which can make crops thrive and improve fruit quality and yield and strengthen resistance to disaster, can be used for common soil and plant in basic fertilizer, additional fertilizer and seed manure. It can be suitable specially for soil with lack of sulfer, but for acid soil, ammonium sulfate needs to be applied with lime.

2. Raw material of making compound fertilizer.

3. In chemical industry, it is used for raw material in making oxydol, ammonia-alum and ammonium chloride; 

4. In Welding Industry, used for welding agent;

5. In textile industry, ued for fire retardant of textile fabrics;

6. In electroplating industry, used for electrobath additive;

7. Ammonium sulfate can be used for making refractory material;

8. catalyst in food coloring reddish brown;

Package: Packed in PP woven bags with PE film liner. Net weight of each bag: 50kgs or 20kgs

Storage and transportation: Stored in cool,dry and ventilated warehouse. It must not be put together with Alkali stuffs,such as lime,cement,etc.Do not expose it to sunlight and rain during transportation .Do not damage the packing bags.
