Manganese dioxide having high bulk density, high tap density and high activity for use in batteries can be obtained by decomposing an aqueous solution of ammonia complex of manganese at a temperature of 68 DEG C. or higher than roasting the resulting manganese carbonate in an atmosphere of oxygen and 15-85% of steam at a temperature of 275 DEG to 375 DEG C. |
