Abstract
The influence of moisture on the nature of interaction of tin dioxide surface with oxygen was followed by using a sensitive surface method a s in situ AC electrical conductivity coupled with analysis of the effl uent. Oscillations of conductivity with various shapes and frequencies were obtained in different experimental conditions, i.e. in isotherma l and non-isothermal regime, at low and high temperature, in flawing g ases with different concentrations of humidity.
