| Abstract: | Porous nanocomposites in the Al2O3-ZrO2 system were studied with a view to understand the selection rules for developing high temperature stable porous oxide systems. The results were also compared with TiO2-Al2O3 nanocomposite systems. The pore structure and phase evolution of these composites were studied using TG/DTA, XRD and nitrogen adsorption/desorption techniques. Al2O3 was found to be a good second phase stabiliser for stabilising ZrO2 and TiO2 matrix phases. |
