摘要：

A colloid-emulsion route is established to prepare yttria stabilized zirconia (YSZ) powder, using cost-effective and commonly available inorganic salts as starting materials. Nanocrystalline, single-phase YSZ powders are prepared via calcinations of emulsion-derived precursor powder at 1000 degreesC for 2 hours. Formation of aggregates is detected, and the aggregates size and morphology depend on the chemical additives nature and milling. After chemical and mechanical treatments, the obtained powder has a spherical morphology, and the aggregates size is homogeneous and around I gm.
