Iron(II) oxide (CAS NO.1345-25-1) is used as a pigment. It is FDA-approved for use in cosmetics and it is used in some tattoo inks.
Iron(II) oxide can be prepared by heating Ferrous oxide in vacuo:
FeC2O4 → FeO + CO + CO2
The black powder can be made less reactive by heating. The heated sample has a more physical change is quenched to prevent disproportionation.Stoichiometric FeO can be prepared by heating Fe0.95O with metallic iron at 770 °C and 36 kbar.
Related compounds: Iron(III) oxide, Iron(II,III) oxide
Ignites when heated in air above 200°C. The powdered oxide may be pyrophoric. Incandescent or hazardous reaction with nitric acid (with powdered oxide), hydrogen peroxide, sulfur dioxide + heat. See also IRON and IRON COMPOUNDS.
