【Abstract】 In this paper, the effect of the alkaline oxide doping on TiO2-V2O5 series sensitive ceramic is studied. The result demonstrated that the alkaline oxide addition and the sintering temperature affect the microstruc-ture and the humidity sensitive characteristics of materials, especially, the sample containing K2O exhibits higher humidity sensitivity. The sample impregnated with polymerizing the tetraethyl orthosilicate, aged in 50℃, 85%RH for 50 hours has improved the humidity sensitivity and the stability.更多还原
