| 摘 要： | 介绍了一种新型管式结构固体电解质CO2传感器。该传感器是将溶胶–凝胶法制备的NASICON材料均匀涂敷在Al2O3陶瓷管上,烧结形成厚膜,加热丝穿过管内提供热量。在加热电流为180 mA,CO2浓度为(200~2000)?06时,管式元件灵敏度曲线的斜率达到60,比同电流下平面型元件的斜率高出14.2。35 d内,管式元件在1 000?06浓度下的漂移值为8.8 mV,与平面型元件的漂移值11.3 mV相比,显示了较好的稳定性。

| Abstract: | Presented was the new-type solid-electrolyte CO2 gas sensor with pipestructure. The sensor was based on the solid-electrolyte NASICON that was spreaded evenly on the Al2O3 ceramic pipe and then sintered into a thick film. A heating wire passed through the pipe interior providing heat. NASICON was prepared by sol-gel process. When heat current is 180 mA, CO2 concentration is in the range (200~2 000)?06, the sensitivity curve抯 slope of the pipe-structure component is 60 mV, which is 14.2 mV more than that of the planar-type component at same current. In 35 days, the float-value of pipe-structure in concentration of 1 000?0-6 is 8.8 mV, it shows better stability comparing with 11.3 mV of planar-type component. |
