                 Decomposition of CO at 650° in presence of Fe₂O₃, Ni₃O₄, and Co₃O₄ is a function of the time and within certain limits depends on the quantity of metallic oxide present.  Whereas at 445° the decomposition is complete, at 650° it is limited, and in presence of Co₃O₄ decomposition ceases when the gaseous mixture contains 61% CO₂ and 39% CO.
