Formation of alumina/zirconia (3 mol% yttria) composite powders prepared by the hydrazine method

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[sub 2] below and above 10 mol% ZrO[sub 2], respectively. The formation process leading to [alpha]-Al[sub 2...

Zusammenfassung:	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[sub 2] below and above 10 mol% ZrO[sub 2], respectively. The formation process leading to [alpha]-Al[sub 2]O[sub 3]-t-ZrO[sub 2] composite powders is examined.
