Sol-gel method in technology of oxide materials

The fundamentals of obtaining highly dispersed powders of oxide materials, including those of complex composition, by the sol-gel method are considered. Various compounds (polyacrylic acid, polyacrylamide, polyvinyl alcohol) were used as a gelling agent in true and colloidal solutions of the main components. When obtaining powders by the sol-gel method, the temperature of synthesis of complex compounds is reduced by 150 - 200 ° C, while the particles are nano-sized.
