一种抗汽油干扰的实用型酒敏元件及其掺杂特性

PETROL INTERFERENCE RESISTIBLE ALCOHOL SENSORS BASED ON SnO 2 AND DOPED BY Sb 2O 3,CaO

介绍了一种抗汽油干扰的、电阻适用的ＳｎＯ２基酒敏元件及其气敏特性，找出了掺Ｓｂ２Ｏ３，ＣａＯ后元件的电阻变化的一些规律．

Sb 2O 3 and CaO were used as dopants to SnO 2, resulting in some changes of its electrical proporty and gas sensitivity. These changes were measured and analyzed. SnO 2 based sensors were made and doped with these dopants. This kind of sensors are sensible to alcohol, unsensible to petrol, and suitable to be taken into actual uses because of their low resistances.
