Barium Nitrate is a salt of barium and the nitrate ion, with chemical formula Ba(NO3)2. It exists as a white solid at room temperature, and at elevated temperatures it decomposes to Barium Oxide, Nitrogen Dioxide and Oxygen:
2Ba(NO3)2 + heat → 2BaO + 4NO2 + O2
Barium nitrate is manufactured by one of two processes. The first process involves dissolving small chunks of barium carbonate in nitric acid – allowing any iron impurities to precipitate – after which it is filtered, evaporated, and crystallized. The second process requires combining barium chloride with a heated solution of sodium nitrate, causing barium nitrate crystals to separate from the mixture.
