Fe(II)O synthesis
I'm wondering if it's possible to make Fe(II)O. Is it even stable under normal conditions? Or will it always be a component of Magnetite FeO-Fe2O4?

FeO can be prepared by the thermal decomposition of iron(II) oxalate.
FeC2O4 → FeO + CO2 + CO
The procedure is conducted under an inert atmosphere to avoid the formation of ferric oxide. A similar procedure can also be used for the synthesis of
manganous oxide and stannous oxide.[3][4]

FeO (wustite) is a high temperature phase which disporportionates at low temperatures into iron and magnetite unless it is cooled very quickly.

So, suppose I made some FeO through decomposition of ferrous oxalate and added some solid CO2 to it. Would it become metastable?

I saw once making FeO from FeCO3. And CO2 released from decomposition of FeCO3 protect FeO.

In 21:25 they started making FeO, in 25:35 they mixed FeO with air and FeO spontaneously catch fire.
