在碱金属氧化物掺杂的ZnSnO_4系气、湿敏材料中掺入LiZnVO_4,既可提高ZnSnVO_4系的湿敏性能,又大大地改善了元件的机械强度,同时使其低温(11%RH)阻值也适中(约10MΩ).通过控制烧结温度、时间及LiZnVO_4的掺杂量,可制得灵敏度高、稳定性较好的湿敏元件.显然,对Zn_2SnO_4-LiZnVO_4系湿敏性能的系统研究,有助于Zn_2SnO_4材料的气、湿敏多功能化. The incorporation of LiZnVO_4 into ZnSnO_4 gas and humidity sensitive material doped with alkali metal oxide can not only improve the humidity sensitivity of ZnSnVO_4 system, but also greatly improve the mechanical strength of the ZnSnO_4 system. At the same time, the low temperature (11% RH) resistance The value is also moderate (about 10MΩ) by controlling the sintering temperature and time and LiZnVO_4 doping amount can be prepared with high sensitivity and good stability of the humidity-sensitive element.Obviously, Zn 2 SnO 4 LiZnVO 4 system performance of the wet- Help Zn2SnO4 material gas, moisture sensitive multi-functional.
