Abstract

In order to improve CO gas sensitivity, $TiO_2$added $SnO_2$ composite ceramics were prepared. Using XRD and SEM, the phases and micro structures of these ceramics were investigated. The resistances as a function of gas atmosphere were measured by High Voltage Measure/Source Unit. The maximum 100 ppm CO gas sensitivities of $SnO_2-TiO_2$composites were 2.5 times larger than that of pure $SnO_2$ composite and showed the obvious temperature dependence of sensitivities in 500, 100 ppm CO gas atmospheres.
