In this paper, the effect of the doping ZnO on the structure and properties ofTiO2-V2O5-Li2O series humid-sensing materials is studied. The result demonstrated thatthe doping ZnO has improved the microstructure, raised the hardness, the sinteringtemperature, the humidity sensitivity and the stability of the materials. The materialwas composed of TiO2 (rutile) and formed the humid-sensing glass of LiZnVO4 in thegrains surface. Particularly, the material A containing low V2O5 exhibits higher porosityand sensi...
