Using the controlled growth technique, nanocrystalline ZrO{sub 2} powders have been prepared from solution. By variation of the Y-content (0--8 mol%), redispersable monoclinic, tetragonal or cubic ZrO{sub 2} powders with particle sizes between 5 and 10 nm were obtained after crystallization at elevated temperature and pressure. Nanodisperse suspensions of the powders have been used for colloidal processing techniques such as tape casting, slip casting or extrusion. The resulting green bodies with densities of 55% and average pore sizes of 5 nm could be sintered at temperatures below 1,100 C leading to monoclinic, tetragonal or cubic ZrO{sub 2} ceramics.
