Calcination - Wikipedia

Calcination refers to heating (thermal treatment of) a solid chemical compound (e.g. carbonate ores) to high temperatures in absence or limited supply air or oxygen (O2), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO3(s)
