Editing Barium nitrate (section)

==Manufacture, occurrence, and reactions==
Barium nitrate is manufactured by two processes that start with the main source material for barium, the carbonate. The first involves dissolving [[barium carbonate]] in [[nitric acid]], allowing any iron impurities to precipitate, then filtered, evaporated, and crystallized. The second requires combining [[barium sulfide]] with nitric acid.<ref name="Ullman2005"/>

It occurs naturally as the very rare mineral nitrobarite.<ref>Mindat, http://www.mindat.org/min-2918.html</ref><ref>{{Cite web|url=https://www.ima-mineralogy.org/Minlist.htm|title=List of Minerals|date=21 March 2011}}</ref>

At elevated temperatures, barium nitrate decomposes to [[barium oxide]]:
