Abstract

Nano-sized Y 2O 3-stabilized ZrO 2 (YSZ) powders were prepared by the spray pyrolysis of solutions containing citric acid and ethylenediaminetetraacetic acid. The resulting hollow particles were heated at between 600 and 900°C and planetary milled to nano-sized powders that showed mixed crystal structures of monoclinic, cubic, and tetragonal phases. Pellets formed from the YSZ powders had fine grains of below 1μm after sintering at 1300 or 1400 °C. Sintering at 1500 °C led to large grains of 2.3 μm.
