Abstract
In the design of ceramic composites, composition is usually determined by mechanical properties. However, in order to promote industrialization of the composites, it is very important to consider the handling of particles. In this study, first composite particles with high dispersion of two components were formed by spray-drying of slurry, which rate of components was varied. And then we pressed and sintered to obtain A1203-Zr02 composite. If the rate of Zr02 was relative high to give the composites tenacity, particles became light and rough, and ability of packing into mold remarkably went down. As a result, its handling must be harder, and then shrinkage increased in sintering. Besides the dispersion state of each component on the surface of sintered body could be quantitatively evaluated by X-ray elementary analysis.
