Abstract

We investigated the electrical and CO sensing properties of ZnO-$TiO_2$ composite ceramics. The electrical conductivities and relative dielectric constants of $TiO_2$ added ZnO increased with increasing $TiO_2$ content in air. The calculated dielectric constants of 3mol%, 5mol%, and 7mol% $TiO_2$ added ZnO were 7, 13, and 120, respectively. The measured CO sensivities were $1{\sim}6.42$ in the temperature range from $100^{\circ}C$ to $400^{\circ}C$.
