Chemical gaseous treatment of SnO2 for a selective detection of gas

Abstract : Heated at 500°C under a SO2 air mixture, tin dioxide is sensitized for different gaseous compounds. Selective detector devices can be imagined with sensor heated at different temperatures or with sensors with time programmed cycliing temperature. An interpretation of the electrical phenomenon based on a potential barrier effect associated with a chemical reaction process is proposed.
