Preparation of $10TiO_2$.$90SiO_2$ Glass by Sol-Gel Process

ABSTRACT

In the present study an attempt was made to synthesize $10TiO_2$.$90SiO_2$ glass by Sol-Gel process. Tetra-ethyl-ortho-silane and titanium-iso-propoxide were used as precursors. As the mutual solvent ethanol and iso-propanol were used. TEOS was partially hydrolyzed with one-fold mole of $H_2O$ prior to the reaction with titanium-iso-propoxide to control the difference of hydrolysis rate of the two metal alkoxides. At gelling temperature higher than 6$0^{circ}C$ it was difficult to obtain monolithic gels. At such a low temperature as 85$0^{circ}C$ clear amorphous gel derived glass with Si-O-Ti bonding was obtained.
