- The polymorphous transformations under the heat treatment of hydroxides in the ZrO(OH)2— Y(OH)3—Ce(OH)4 system depending on precipitation technique (coprecipitation or sequential precipitation) and chemical composition have been investigated. It has been shown that the stabilization degree of high-temperature tetragonal modification and time structure stability of solid solutions [1–(x+y)]ZrO2⋅xY2O3⋅yCeO2 with partial substitution of yttrium for cerium increase in the compositions with x +y > 0.03. The possibility to obtain nanocrystalline particles (15—20 nm) of hydroxides under heat treatment has been shown.
