| Abstract |
[TiO_2] sol and SiO_2 sol were prepared using sol-gel method. As H_{2}O/Alkoxide ratios increased, sol had cluster structure and as H_{2}O/Alkoxide ratios decreased, sol had linear structure. Gelation time of TiO_2 sol was faster than that of SiO_2 sol according to the time. In comparison with initial viscosity between TiO_2 sol and SiO_2 sol, TiO_2 sol was highest at H_{2}O/Ti(OC_{3}H_{7})_{4}=5, SiO_2 sol was almost constant according to H_{2}O/Si(OC_{2}H_{5})_{4} ratios. |
