Application of Metal Alkoxides in the Synthesis of Oxides,
Abstract
Powders and thin films of the following simple and complex oxides have been obtained from metal alkoxides: M(11)TiO3 (M=Mg, Ca-Ba), MM1/3B2/3O3 (M=Sr,Ba,M'=Mg-Zn; B=Nb,Ta); MNbO3(M=Li,Na); ZrTiO4; PbTiO3; PST, PLZT-materials; M2BO4 (M=Li,Na; B=Mo,W), Bi2BO6(B=Mo,W); Li sub x WO3, WO3, MoO3, Bi2O3-WO3(solid 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 M(OR)n with elimination of ether and formation of oxoalkoxides, containing M-0-M' bonds - the basis of future oxide phases.
