Technological Aspects of Preparation of High-Purity Compounds for Sol-Gel and Pyrolytic Synthesis Methods

摘要

A number of aspects associated with the synthesis of high-purity compounds used in the gas-phase and sol-gel methods for preparing coatings and finely dispersed powders of oxides and oxide composites are considered.In recent years,alcoholates(alkoxides)of elements(Si,B,Ge,Ti,etc.)with the general formula El(OR)_n,where R is a hydrocarbon radical(as a rule,C1-C5),have attracted the particular attention of researchers as promising materials for the use in the technology for synthesizing high-purity compounds,specifically,oxides,oxynitrides,and composite materials of different chemical compositions.
