Do you know what is ammonium nitrate? and why it is so dangerous?
Ammonium nitrate Introduction Definition Ammonium nitrate is a crystalline white solid. Its made in large quantity industrially by the reaction of ammonia with concentrated nitric acid. The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid. NH3 + HNO3 → NH4NO3 Ammonia is used in its anhydrous form (a gas) and nitric acid is concentrated. After the solution is formed, typically at about 83% concentration, the excess water is evaporated off to leave an ammonium nitrate(AN) content of 95% to 99.9% concentration(AN melt), depending on grade. The AN melt is then made into “prills” or small beads in spray tower, or into granules by spraying and tumbling in a rotating drum. The prills or granules may be further dried, cooled, and then coated to prevent caking. These prills or granules are the typical AN products in commerce. Applications Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). It is less c
