| 摘 要： | 在WO3粉体材料中,加入一定量的添加剂(Pt,Pd,PtO2,PdCl2,SnO2,SiO2和Al2O3),于600℃烧结1h,制成旁热式厚膜丁烷气敏元件。采用静态电压测量法,研究了元件的加热功率与元件灵敏度(β)的关系以及添加剂对元件的响应与恢复时间的影响。结果表明:掺入质量分数为0.5%的PdCl2,在加热功率为600mW时,丁烷气敏元件的灵敏度提高约12倍,元件的响应和恢复时间分别缩短约70%和85%。

| Abstract: | The indirectly heat type thick film butane gas sensor was prepared by mixing additive (Pt,Pd,PtO2,PdCl2,SnO2,SiO2 and Al2O3) into WO3-based and heating for one hour at 600 ℃. Based on the static voltage measure method,the relation between the heat power and the sensitivity of sensor,and the effect of additive on response and recovery time for different additive were studied. The results show that the sensitivities of butane gas sensor are increased about 12 times by doping 0.5% PdCl2 (mass fraction) at 600 mW heat power and its response time and recovery time are decreased about 70% and 85%,respectively. |
