Abstract
Yttria-stabilized tetragonal zirconia powders have been synthesized by reaction in molten salts at 450-degrees-C. To obtain a Y2O3-ZrO2 Soli d solution powder, it was necessary to use yttrium salts (not yttrium oxide directly) in molten NaNO3-KNO3 eutectic. The agglomeration state of the powders depended on their washing conditions. An alcohol-washe d powder containing soft agglomerates led to a fine-grained and high-d ensity sintered body.
