Relationship between powder characterization using an image analysis and sintering characteristic

摘要

This paper reports a new approach for characterization of thepowder using image analysis. Through the use of image analysis forcharacterization the processing and properties of ceramics could be effectivelycontrolled. Image analysis is based on the detailed particle shape analysis by SEMmicrographs. We examined two kinds of SiO_2 have same particle sizedistribution and zeta potential, but the green sheet density and sintering behaviorare different. A comparison of the results of the image analysis revealed adeference in the shape and state of agglomeration of particles. In the ball-millingprocess, shape factor of particles affects the behavior of breaking-up of particlesinto small pieces. Green sheet density was found to depend on the state of thepacking of particles, that is, the state and size distribution of agglomerates.Sintering behavior was also closely connected with green sheet density.
