Electrical conduction and gas sensing characteristics of 15Fe2O3–5ZnO–80TeO2

Abstract The dc conductivity of 15Fe 2 O 3 –5ZnO–80TeO 2 glass system (mol%) has been measured from room temperature to 180 °C. Ceramic pellet of this glass was investigated for its use as a possible inexpensive oxygen gas sensor. The ceramic sample responded quickly to oxygen environment and the gas sensitivity was found to be ∼ 10.5. The possible mechanism for oxygen sensing may be attributed to the surface adsorption of gas followed by bulk diffusion.
