This paper reports a new approach for characterization of the powder using image analysis. Through the use of image analysis for characterization the processing and properties of ceramics could be effectively controlled. Image analysis is based on the detailed particle shape analysis by SEM micrographs. We examined two kinds of SiO_2. These two SiO_2 have same particle size distribution and zeta potential, but the green sheet density and sintering behavior are different. A comparison of the results of the image analysis revealed a deference in the shape and state of agglomeration of particles. In the ball-milling process, shape factor of particles affects the behavior of breaking-up of particles into small pieces. Green sheet density was found to depend on the state of the packing of particles, that is, the state and size distribution of agglomerates. Sintering behavior was also closely connected with green sheet density.
