Forming of Ceramic Powders by Cyclic-CIP

Abstract

The effect of the bias pressure of Cyclic-CIP. on the bulk density of alumina compact was examined, and the following results were obtained.(1) When the maximum pressure is constant, the high bulk density can be obtained with decreasing bias pressure.(2) Relative bulk density of 74.2% was obtained under the condition of 100MPa in maximum pressure, 0MPa in bias pressure and 10000 cycles.(3) In order to obtain the same bulk density, the maximum pressure of C-CIP can be decreased over one-tenth of that of static-CIP.
