Abstract
SnO2system nanometer powders are prepared by coprecipitation with urea.The influence of the amount of liquid-doped LiZnVO4on the microstructure and humidity sensitive characteristics of SnO2is studied.The characteristics of frequencies is analyzed.The experimental results show that the microstructure of the material is characterized by suitable rod-shaped grains and the properties of humidity sensitive material are better if SnO2system nanometer powders are prepared by co-precipitation with urea and the amount of liquid-doped LiZnVO4is well controlled.
