                  When finely divided ferric oxide is heated at 445° in sealed tubes with pure and dried CO, the decomposition of the latter is a function of the time and of the quantity of ferric oxide present. The quantity of CO₂ formed increases regularly and eventually the decomposition is complete.  Similar experiments are being made with Co and Ni oxides at 445° and with all 3 oxides at higher temperatures.
