Fe2O3/ZnO复合氧化物气敏元件的制备与性能
摘要
以Fe2O3和ZnO为原料
直接混合烧结制得7种不同烧结温度和原料配比的Fe2O3/ZnO复合氧化物元件
并对其进行气敏性能测试
结果发现:不同烧结温度和原料配比的Fe2O3/ZnO复合氧化物元件对不同的气体有不同的气敏性
烧结温度为800℃
Fe2O3∶ZnO摩尔比为0.5∶1的气敏元件对硫化氢具有较好的气敏综合性能。
Abstract
Fe2O3/ZnO composite oxide elements are prepared by sintering the mixture of Fe2O3 and ZnO
and their gas sensitivity are studied.The results show that the gas sensitivity of the Fe2O3/ZnO composite oxide elements prepared in different molar ratios and at different sintering temprature is different to different gas
and the element which Fe2O3∶ ZnO molar ratio is 0.5∶ 1 and sintering temprature is 800 ℃ has a higher gas sensing comprehensive performance to H2S.
