Abstract

The xerogels in the system 0.88 mol % ZrO2–0.12 mol % CeO2 were obtained by the method of coprecipitation in a neutral (pH 7) and slightly alkaline (pH 9) medium under the influence of ultrasound with the size of the agglomerates of 70–230 nm. It is shown that the coprecipitation of hydroxides of zirconium and cerium at pH 9 with the use of ultrasonic treatment facilitates the formation of primary crystalline particles in the xerogel, whose size is ~ 5 nm, whereas the xerogel synthesized in a neutral environment consists only of the X-ray amorphous phase. The effect of pH precipitation on deposition processes of dehydration of the xerogels and crystallization of the solid solution based on zirconia oxide in the metastable pseudocubic modification (с'-ZrO2) was discovered. It was found that, in the temperature range of 500–800°C, there is a phase transition с'-ZrO2 → t-ZrO2; the size of the crystallites of the formed tetragonal solid solutions is 8 and 11 nm. The dispersion properties and characteristics of the pore structure of the powders of the solid solution Zr0.88Ce0.12O2 were investigated by the method of low-temperature nitrogen adsorption. It is determined that the specific surface area of t-ZrO2 samples obtained after firing at 800°C is 117 and 178 m2/g, the total pore volume reaches 0.300–0.325 cm3/g, and the pore size distribution is monomodal and is in the range of 2–8 nm. The effect of thermal “aging” at a temperature of 800°C (40 h) on the structure and dispersion of the solid solution t-ZrO2 powders was studied.
