Abstract

$TiO_{2}-Nb_{2}O_{5}$ sol was prepared using sol-gel method. DTA properties of gel powder had endothermic reaction due to evaporation of propanol and water about $78^{\circ}C$, had exothermic reaction due to propanol combustion about $290^{\circ}C$ and had exothermic reaction due to changing of $TiO_2$ phase about $640^{\circ}C$. Capacitance of thin films increased according to increasing relative humidity, whereas it decreased according to increasing measured frequency.
