摘要
Alumina/3 mol% yttria-doped zirconia composite powders have been prepared by the hydrazine method. As-prepared powders are AlO(OH) gel solid solutions and the mixtures of this and amorphous ZrO2 below and above 10 mol% ZrO2, respectively. The formation process leading to alpha-Al2O3-t-ZrO2 composite powders is examined.
