摘要：

CTO powders and thin films have been prepared by a sol-gel route and subsequent thermal treatment at low temperature (<= 400 degrees C). The humidity characteristics of CTO thin films have been investigated. Results reported have shown that the humidity behaviour is related to the intergranulary porosity of the films. The Cr/Ti ratio and the role of alkaline impurities (Li+) was also studied with aim to clarify the mechanism of the surface conduction of CTO films in the presence of water vapor.
