In this study, composite particles were prepared by dispersing fine powder particles (mean diameter 0.2μm) on core particles (mean diameter 12μm) by dry coating. This paper shows a new method of quantitatively evaluating the state of fine powder particle dispersion on the surface of each core particle by image analysis. The findings are summarized as follows:<BR>The state of fine powder particle dispersion on the surface of each core particle was successfully evaluated by degree of dispersion.<BR>Evaluation of the dispersion state by degree of dispersion was verified by the coefficient of variance for the relative intensity of the characteristic X-ray from fine powder particles and powder layer brightness on each composite particle.<BR>Image analysis makes it possible to obtain the diameter of each fine powder particle dispersed on the surface of a composite particle. The process in which fine powder particles are dispersed in the form of primary particles was thus clarified. Optimum operation time for obtaining composite particles having fine powder particles dispersed thereon was found on the degree of dispersion and the measurement of the diameters of fine powder particles.
