摘要: The microstructure and surface properties of highly dispersed ceria samples various chemical thermal histories have been studied using mercury porometry, low-temperature nitrogen adsorption, scanning electron microscopy. Thermal decomposition precursor salts under relatively mild conditions (<350°C) yields CeO 2 powders with fractality (2 < D 3). prepared freeze drying are characterized by two organization levels, each level it own fractal dimension.
