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 ZrO 2 below and above 10 mol% ZrO 2 , respectively. The formation process leading to α–Al 2 O 3 – t ‐ZrO 2 composite powders is examined.
