TEMPLATE EFFECT OF THE M~(3+)- CATIONS IN THE COURSE OF THE SYNTHESIS OF HIGH DISPERSED TITANIUM AND ZIRCONIUM PHOSPHATES

摘要

An explanation of the template effect of the M~(3+)-cations in the course of the sol-gel synthesis of high dispersed titanium and zirconium phosphates is presented. Some ways to vary and to control the porous structure of such phosphates are shown and proposed.
