The objective of this study was to produce well‐dispersed nanosized yttria tetragonally stabilized zirconia (Y‐TZP) powder in aqueous suspension. The Y‐TZP powder was produced by precipitation from homogeneous solution at 200°C under hydrothermal conditions. A homogeneous solution was created through the use of a complexing agent, which subsequently could be used in a dispersion scheme developed for the nanosized Y‐TZP powder. Characterization of the Y‐TZP powder was performed using X‐ray diffraction, Raman spectroscopy, X‐ray fluorescence, and high‐resolution transmission electron microscope. The overall goal of this study is the eventual production of bulk ceramics from well‐dispersed nanosized aqueous ceramic suspensions via wet processing techniques.
