National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Application of Metal Alkoxides in the Synthesis of Oxides.

ADP006653

Publication Date	1991
Personal Author	Yanovskaya, M. I.; Turevskaya, E. P.; Kessler, V. G.
Page Count	10
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.
