Abstract
Recently, the ceramics are used in various fields. Especially, electro ceramics which have specific electric function are taken notice. Then, electro ceramics manufacturing process become more and more important in industry.The ceramics manufacturing process consists of various kinds of unit operations, and can be considered as combination of forming process and sintering one. However, basic relation between forming process and sintering one has not yet been elucidated. In other words, the effect of the homogeneity of initial bulk density distribution in the forming cell on the homogeneity of bulk density of powder compact or sintered powder one has not yet discussed.
In this paper, the effects of initial bulk density distribution on the bulk density distributions of powder compact and sintered powder one are experimentally discussed by using the X-ray radiograph system. As the result, these bulk density distributions of powder compact and sintered one are greatly effected on the initial bulk density.
