Abstract
Yttria-stabilized zirconia (YSZ) powders have been prepared by basic hydrolysis of a solution containing zirconium isopropoxide and yttrium nitrate. Crystallization of cubic YSZ occurs near 450 °C yielding ceramic powders with high specific areas, the values of which are dependent on the ammonia and water contents of the hydrolysis solution. Sintering at 1420 °C yields ceramics with nearly theoretical density and homogeneous grain size distribution.
