摘要：

In order to improve the long-term stability of SnO2 sintered gas sensors, 31 kinds of metal elements have been added and their stability over a long period of time studied. Sensor materials with metal element dopants are characterized by measurements of hydrogen oxidation reactivity and X-ray diffractometry. The addition of rhenium and vanadium results in excellent stability, reducing the changes in hydrogen oxidation reactivity of the sensor elements over a long period of time. The X-ray analysis indicates that these addition effects are independent of the inhibition of SnO2 crystallite growth.
