ZnCr_2O_4-V_2O_5-Li_2O-ZnO湿敏材料的气体选择性研究

Research on Gas selectivity of the humidity-sensitive material ZnCr_2O_4-V_2O_5-Li_2O-ZnO

测试了ZnCr2O4-V2O5-Li2O-ZnO感湿体在H2、CO2、煤气、酒精蒸汽等气体环境中电阻的变化情况。结果表明,电阻值明显随环境温度变化但基本不受气体影响。

Have tested the resistance of the humidity-sensitive material ZnCr2O4-V2O5-Li2O-ZnO in different gas surroundings, such as hydrogen, carbon dioxide, coal gas and ethanol （steam）. It indicates that the resistance is independent of the gas, however the temperature affects the resistance obviously.
