| Abstract: | Sensitivity and selectivity of Al2O3 thick films for LPG gas sensor have been examined. The structural properties of Al2O3 have been examined by means of XRD and the surface morphology by the SEM studies. XRD confirmed the complete phase formation at 800oC for 6 h. The sensing properties and response time of (1 wt%) Pd:(10 wt%) Cr2O3 doped Al2O3 have been characterized by d.c. electrical measurements for different gases. The element is exposed to several gases such as LPG, CO, CH4 in dry air. It shows good sensitivity and selectivity towards LPG at low operating temperature. |
