摘要
采用金属有机物热分解（ＭＯＤ）法制备了ＳｎＯ_２酒敏元件，ＸＲＤ和ＡＥＳ谱表明热处理后己酸亚锡已转化为ＳｎＯ_２。此外还证实ＳｎＯ_２元件的内电势是加热丝偏位引起的热电势。元件的主要技术指标为：灵敏度＞８，选择性＞６，响应时间＜５ｓ，恢复时间＜３０ｓ。
SnO2-base ethanol-sensing components have been made by metallorganic deposition (MOD). By XRD and AES, it is shown that after heat trteatment, tin Caproate have been changed into SnO2.It has been also proved that the interior potential of the SnO2component is thermoelectric potential introduced by heater dislocation. Main technical characteristics of the components are:sensitivity>8, selectivity>6, response time<5 s, recover time<30 s.
