| 摘 要： | 在WO3粉体材料中加入质量分数为4%的瓷粉和不同质量分数的金属氧化物(SnO2,SiO2,Al2O3),以恒温600℃烧结1 h制成旁热式厚膜可燃性气敏元件。采用静态电压测量法,研究了元件的加热电压与元件灵敏度的关系。实验结果表明:WO3基元件掺入一定量的金属氧化物在加热功率为600mW时能提高元件的灵敏度。

| Abstract: | Mixing 4% of porcelain powder and different quality fraction metal-oxides(SnO2,SiO2,Al2O3) into WO3-based and heating for 1h at stable 600℃,the heating type thick film combustible gas sensitive sensor can be manufactured.Based on the experiments and adopting steady voltage measuring method,the relationship between the heat voltage and the sensitivity of sensor is studied.Experiment results show that the sensitivities of WO3-based combustible gases sensitive sensor are improved by doping different quality fraction metal-oxides with the tepefaction power at 600mW. |
