On the preparation of the raw powder of the tantalum solid electrolytic capacitor, the effects for the propertiy of treated powder of particle size and composition of PMMA binder and spray treatment has been studied with the proposed frequency difference distribution method. This method is expresed as the difference in frequency of particle size distribution between raw and treated powder.<BR>It was found that the mean particle diameter of the treated powder using the binary system of PMMA binder (8μm-1.25%, 1.5μm-0.75%) together with spray pre-treatment is the smallest.<BR>The binary system of PMMA binder(8μm-1.25%, 1.5μm-0.75%) is suggested as optimam composition of PMMA binder for the grinding and homogeneity of raw powder. It was shown that the proposed frequency difference distribution method is useful for the analysis of preparation mechanism of the raw powder.
