| Abstract: | SnO2 system nanometer powders are prepared by co-precipitation with urea. The influence of the amount of liquid-doped LiZnVO4 on the microstructure and humidity sensitive characteristics of SnO2 is 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 SnO2 system nanometer powders are prepared by co-precipitation with urea and the amount of liquid-doped LiZnVO4 is well controlled. |
| Keywords: | microstructure humidity sensitive characteristics composite impendence properties frequencies properties |
