报道了在Ｉｎ２Ｏ３材料中分别掺杂一定比例的Ｐｄ，Ｆｅ２Ｏ３，ＳｎＯ２，ＣａＯ和ＭｇＯ材料后敏感材料的气敏特性．实验结果表明，掺杂及烧结温度对Ｉｎ２Ｏ３材料的气敏特性有较大的影响．
The gas sensing properties of sensitive materials after doping a certain proportion of In2O3 with Pd, Fe2O3, SnO2, CaO and MgO were reported. The experimental results show that the doping and sintering temperature have a great influence on the gas sensing properties of In2O3.
