摘要
以SnO_2为基体的气敏元件分辨率通常较低,本实验通过制备超细粉体Sn(OH)_4,掺杂La_2O_3直接烧结制出灵敏度高、稳定性好、分辨率高的乙炔气体敏感元件,对烷烃类及烟雾等杂散气体分辨率较高。
By making fine powder of Sn(OH)4 adulterated with La2O3, the sensor exhibits high sensitivity and easily distinguishes Ethyne from other gases. The sensitivities and responses mechanism to Ehtyne has also been investigated.
