摘要
氧化锡气敏材料的电导率以及对气体的选择性由氧空位的形成和氧化过程共同完成，氧空位浓度越大，气敏效应越明显。根据氧化锡的这一气敏机理，本文研究了添加剂Ｓｂ２Ｏ３和ＰｄＣｌ２对氧化锡气敏材料电导率及选择性的影响。
The conductivity and the gas seletivity of SnO 2 gas sensing material are carried out with the formation of lacking oxygen and oxidizing process.The higher the density of lacking oxygen is,the more the gas sensing effect is obvious.According to the gas sensing mechanism,the influence of additives of Sb 2O 3 and PdCl 2 on the conducdivity and the selectivity of SnO 2gas sensor is studied here.The applied mechanism of additive on the gas sensing characteristics of SnO 2 is analyzed.
