The production of ceramics having high density, low porosity, and fine grains requires the use of high-purity metal oxide powders that consist of particles of uniform shape, size, and composition. Metal Alkoxide hydrolysis is an attractive method for the synthesis of high-purity metal oxide particles. The nature of the precipitate formed is affected by the solvent. This present study investigates the growth kinetics and characteristics of metal oxide particles (i.e., ZrO/sub 2/ and TiO/sub 2/) that are produced in various alcohol solvents (ethanol, 1-butanol, 2-butanol, and tert-butyl alcohol). Results are also presented for the synthesis of uniform homogeneous composite metal oxide particles (i.e., Y/sub 2/O/sub 3/-ZrO/sub 2/ and ZrO/sub 2/-TiO/sub 2/) by low-temperature metal alkoxide hydrolysis. 3 figs., 7 refs.
