Editing Iron(II) oxide (section)

==Preparation==
FeO can be prepared by the thermal decomposition of [[iron(II) oxalate]].
:{{chem2|FeC2O4 -> FeO + CO2 + CO}}
The procedure is conducted under an inert atmosphere to avoid the formation of iron(III) oxide ({{chem2|Fe2O3}}).  A similar procedure can also be used for the synthesis of [[manganous oxide]] and [[stannous oxide]].<ref>H. Lux "Iron (II) Oxide" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G.
