Abstract: The oxygen utilization rate is low in manganese tetroxide preparation by metallic manganese powder suspending liquid process. It is demonstrated by the test that the addition of catalyst or hydrocarbon compound can improve the oxygen utilization rate and if the two are added in a well matched ratio, the oxygen utilization rate will be greatly raised without over-oxidation.
