In general manufacturing process of ceramics with dry compaction, quantitative analysis of each element of the process and of whole process is necessary. In this study, it is clearified that the diameter of spray-dried granulated Al2O3 particle can be controled effectively by choosing rotation rate of atomizer. We showed that apparentdensity of green-compact is greatly influenced by apparent density of granulated Al2O3 particle, especially at low compaction pressure. Both granulated Al2O3 particle and the green-compact have higher density, if concentration of slurry is relative high. And then, only density of sintered Al2O3 jumps up at about 57 wt%. So. we decide that the optimum concentration is 57.0 wt%, where there is no problem on this condition.
