Variations in electrical conductivity of SnO2 thick film exposed to ethanol vapor before and after aging process were investigated. Aging is performed continuously at 350-750ºC and 96 hours. The Results show that room conductivity (Iair) decreases with aging temperature. However, the maximum conductivity in presence of ethanol (IMAX g) remains approximately constant. Consequently, these variations result in the increase of electrical conductivity of tin oxide layer.
