Abstract:

Powders and thin films of the following simple and complex oxides have been obtained from metal alkoxides M11TiO3 MMg, Ca-Ba, MM13B23O3 MSr,Ba,MMg-Zn BNb,Ta MNbO3MLi,Na ZrTiO4 PbTiO3 PST, PLZT-materials M2BO4 MLi,Na BMo,W, Bi2BO6BMo,W Li sub x WO3, WO3, MoO3, Bi2O3-WO3solid solutions, YFeO3,Y3Fe5O12 YBa2Cu3O7-x Bi2Sr2CaCu2Ox Bi2Sr2Ca2Cu3Ox. For synthesis of metal alkoxides and solutions containing two or more elements electrochemical technique the anodic dissolution of metals in alcohols has been used. Analysis of different examples emphasises that considerable attention in sol-gel chemistry of oxides should be paid to decomposition of MORn with elimination of ether and formation of oxoalkoxides, containing M-0-M bonds - the basis of future oxide phases.
