摘要

Gd_(0.1)Ce_(0.9)O_(1.95) ceramics were prepared using a simple and effective process in this study. Without any prior calcination, the mixture of raw materials was pressed and sintered directly. The reaction of the raw materials occurred during the heating up period by passing the calcination stage in the conventional solid-state reaction method. More than 99.5 percent of theoretical density was obtained for Gd_(0.1)Ce_(0.9)O_(1.95) sintering at 1500-1600 deg C. Fine grains (<1 (mu m) formed in pellets sintered at 1450 deg C. The homogeneity of grains increased with the sintering temperature. The grains grew to >4.5 mu m in pellets sintered at 1600 deg C. The reactive-sintering process is proved to be a simple and effective method in preparing Gd_(0.1)Ce_(0.9)O_(1.95) ceramics for solid electrolyte application.
