摘要

Porous and dense ZrO_2-4 mol.% Y_2O_3 ceramics were fabricated by spark plasma sintering at 1100 and 1500 °C. The porosity of the ceramics sintered at 1100 °C increased with the addition of ~0-5 mol.% Gd_2O_3. In contrast, the ceramics sintered at 1500 °C showed full density regardless of the amount of Gd_2O_3 addition. The fluorite-type Gd_2Zr_2O_7 phase was formed as the second phase in the tetragonal ZrO_2 matrix. The thermal diffusivity and thermal conductivity of sintered ZrO_2-4 mol.% Y_2O_3 decreased with increasing Gd_2O_3 addition.
