Ammonium Nitrate Facts and Uses

Ammonium Nitrate Facts and Uses Ammonium nitrate is the nitrate salt of the ammonium cation. It may be considered the ammonium analog to potassium nitrate or saltpeter. Its chemical formula is NH4NO3  or N2H4O3.  In pure form, ammonium nitrate is a crystalline white solid that readily dissolves in water. Heat or ignition readily cause the substance to ignite or explode. Ammonium nitrate is not considered toxic. Options for Obtaining Ammonium Nitrate Ammonium nitrate may be purchased  as a pure chemical or  collected from instant cold packs or some fertilizers.  The compound is most commonly prepared by reacting nitric acid and ammonia. Its also possible to prepare ammonium nitrate from common household chemicals. While it is not difficult to make ammonium nitrate, it is dangerous to do so as the chemicals involved can be hazardous. In addition, it can easily become explosive when mixed with fuels or other chemicals. Ammonium Nitrate Uses and Sources Ammonium nitrate is a chemical compound used in agriculture as a fertilizer, to make pyrotechnics, as an ingredient in cold packs, and for science demonstrations. Its also used to create controlled explosions in mining and quarrying. It was once mined as a natural mineral (niter) in the deserts of Chile, but it is no longer available except as a man-made compound. Because ammonium nitrate may be misused, it has been phased out in many countries.
