N2 - Electrophoretic deposition (EPD) is a well-known ceramic formation method and has been widely researched since the 1950s. However, few studies have tried to use EPD to apply high concentration slurry, and few have been used practically. Electrophoretic deposition behavior of high concentration (51.8 vol% solids) pottery slurry and the microstructure of the formed body was investigated in this study. The deposition rate was directly proportional to the electrophoretic time. The slurry was composed of many kinds of minerals that have different charges, such as clay, feldspar, quartz, and so on. The chemical composition of the formed body was homogeneous and equal to that of the slurry in the deposition direction in spite of charge differences. To clarify this, the slurry composition system was simplified to two materials, such as Al2O3 and SiO2, which have obviously different surface charges, and the EPD behavior of the slurry was investigated. In a high-concentration (11.9 vol% solids) slurry of this system, the chemical composition of the formed body was homogeneous and equal to that of the slurry. In this case, it is thought that the particle charge made less contribution to the mobility of particles in electric field.
