EFFECT OF THE PREPARATION CONDITIONS ON THE PHASE COMPOSITION AND TEXTURE OF MESOPOROUS ZIRCONIUM DIOXIDE

Changes in the phase composition and textures of zirconium dioxide depending on the composition of the reaction medium and the conditions of the subsequent hydrothemal and thermal treatment have been elucidated. The conditions for preparing uniformly mesoporous zirconium dioxide with pore sizes of 50-64 Å have been determined. It has been established that treatment of zirconium dioxide hydrogel in alkaline solutions facilitates the formation of nano-sized particles, stable to agglutination.
