Abstract

Halogenoalkoxides are promising molecular precursors useable in sol-geltechnology. They exhibit a lower sensitivity towards hydrolysis than commonalkoxides and so appear to be easier to handle. Some data about thestructure of titanium chloroalkoxides, pure and with the addition of acontrolled amount of water, were obtained using FT-Raman, while the effectof thermal treatment under nitrogen or oxygen was studied using TGA-IRcoupling. Finally the oxide products were characterized by Raman and byED-XRMA, proving mat chloroalkoxides could be used as molecular precursorsof oxide by sol-gel process. We showed that TGA-FTIR coupling is a powerfultool in order to study a thermal treatment and could be used to optimizeit.
