Abstract

Halogenoalkoxides are promising molecular precursors useable in sol-gel technology. They exhibit a lower sensitivity towards hydrolysis than common alkoxides and so appear to be easier to handle. Some data about the structure of titanium chloroalkoxides, pure and with the addition of a controlled amount of water, were obtained using FT-Raman, while the effect of thermal treatment under nitrogen or oxygen was studied using TGA-IR coupling. Finally the oxide products were characterized by Raman and by ED-XRMA, proving mat chloroalkoxides could be used as molecular precursors of oxide by sol-gel process. We showed that TGA-FTIR coupling is a powerful tool in order to study a thermal treatment and could be used to optimize it.
