摘要：
The experimental results of two type thick film SnO2 gas sensors are reported in this paper. The sensors based on SnO2 powders prepared by cc-precipitation are called sensors-c, and the sensors based on SnO2 powders prepared by hydrothermal synthesize are named sensors-h. The experimental results show that the sensitivity and selectivity of sensors-h for many type gases such as i-C4H10, H-2, C2H5OH, CH4 and CO are higher than those of sensors-e for the same gases. The influence of heating voltage on the stability of sensors and the great differences between properties of sensors-h and of sensors-c are explained by SEM and XRD analysis.
