An investigation has been made of the solid-state formation of manganese ferrite in the reducing atmosphere of carbon monoxide gas. Formerly some reports pointed out that for the formation of manganese ferrite, lowering partial pressure of oxygen in the firing atmosphere is effective to draw down the reaction temperature. This, however, has scarcely been taken up in other reports. In this report, the authors has confirmed by means of X-ray analysis a fact that carbon monoxide used as a reducing atmosphere is quite effective for lowering the formation temperature of manganese ferrite. In addition to this effect, this method showed many advantages as mentioned below. (1) Decomposition of the product by oxidation can be prevented and the time required for this reaction can be shortened considerably. (2) The reaction mechanism of the formation is simplified and as the result of this the product tends to be composed of a single chemical species. (3) This simplification may enable kinetic analysis of the reaction.
