✦ Synopsis

ZrO~2~(3Y) nano‐sized powders have been synthesized by chemical coprecipitation technique. The gelcasting‐pressing (gel‐casting and dry pressing) method and pressureless sintering were applied to fabricate Y‐TZP nanoceramics. A fully dense pellet of ZrO~2~(3Y) is obtained after sintering at 1250 °C for 2h, the reason for the good sintering behavior is believed to be both the increase in relative density and the decrease in pore size.

## Abstract BaZr~0.9~Y~0.1~O~3‐δ~ has been synthesised by three different methods: the solid‐state reaction, the spray pyrolysis and the spray drying. Significantly different apparent lattice parameters (between 0.4192 nm for the sample prepared by the solid‐state reaction method and sintered at 1,
