Abstract

In order to investigate CO sensing property of a SnO$_2$-WO$_3$composite ceramic. we prepared pure SnO$_2$and WO$_3$added SnO$_2$compostie ceramics. Using XRD and SEM, a phase analysis and microstructure were investigated. The resistances as a function of gas atmosphere were measured by High Voltage Measure/source Unit. The measured 1000ppm CO gas sensitivity of SnO$_2$-WO$_3$composite ceramics were smaller than that of pure SnO$_2$.
