Ammonium Chloride
Molecular formula:NH4Cl
Molecular weight:53.5
CAS No.:12125-02-9
Property:White crystal powder, taste salt and cool. Specific gravity is 1.527. Sublimating or dividing when heating, absorbing moist and caking in the moist and raining weather. It'll corrode black metal and other metal. Soluble in water, soluble in liquid ammonia, slightly soluble in alcohol, insoluble in acetone and ether. Sublimation if heating to 340℃, decomposed to ammonia and hydrogen chloride if heating to 400℃.
Usage:

1. Technical grade used in making dry-battery and storage battery, ammonium salt, electroplating, electrode, photograph, precision casting, tanning, medicine, bonding agent.

2. Agriculture grade used as a nitrogen source in fertilizers, it is a kind of available nitrogen with physiological acidity, and its normal nitrogen content is between 22%~25%, the hygroscopicity is larger than ammonium sulfate, and smaller than nitramine. The ammonium chloride fertilizer grade normally is noncaking. It can be used in neutral soil and carbonate soils. It also can directly used in food crop and rape, but it mainly in compound fertilizer as materials.

Packing:Net in 25KG/50KG/1000KG plastic woven bag.
