Abstract Scope Strong texture is achievable in 3Y-TZP by a reactive texturing technique. In suspensions containing monoclinic zirconia the (100) plane can be oriented perpendicular to the magnetic field direction during green forming. When 8Y cubic zirconia is added, a strong texture in the single phase 3Y-TZP is obtained after full reaction between both phases. The (001) plane of the tetragonal phase is perpendicular to the magnetic field with a texture index of 32.5. In contrast, for Ce-TZP a similar strategy meets with less success. The reacting phases are monoclinic zirconia and cubic ceria. The resulting texture of Ce-TZP formed is considerably weaker with a texture index of about 3. For successful reactive texturing of zirconia the differences in composition between the monoclinic and the cubic phases should be small. The texture in the resulting microstructure depends on the details of the phase transformations taking place during the homogenizing sintering treatment.
