tAl2O3and ZrO2monoliths as well as layered Al2O3/ZrO2composites with a varying layer thickness ratiowere prepared by electrophoretic deposition. The sintering shrinkage of these materials in the transversal(perpendicular to the layers, i.e. in the direction of deposition) as well as in the longitudinal (parallelwith layers interfaces) direction were monitored using high-temperature dilatometry. The sintering oflayered composites exhibited anisotropic behaviour. The detailed study revealed that sintering shrinkagein the longitudinal direction was governed by alumina (material with a higher sintering temperature),whilst in the transversal direction it was accelerated by the directional sintering of zirconia layers. Forinterpretation of such anisotropic sintering kinetics, the Master Shrinkage Curve model was developedand applied. Crack propagation through laminates with a different alumina/zirconia thickness ratio wasdescribed with the help of scanning electron microscopy and confocal laser microscopy.
