摘要
研究了α－Ｆｅ２Ｏ３（ＳＯ）气敏材料和Ｆｅ２Ｏ３试剂和在不同烧成温度和工作温度下的红外吸收性质，结果表明ＳＯ改变了α－Ｆｅ２Ｏ３的结构状态，使ａ－Ｆｅ２Ｏ３产生氧吸附功能，从而获得气敏性。
The infrared absorption properties of gas sensitive material a-Fe2O3(SO)and reagentFe2O3 were studied at the different sintering and working temperatures.The results indicatethat structural state of a-Fe2O3(SO) was changed by the sulphate ions leading to itsoxygen absorption function,and its gas sensitivity is thus obtained.
