空心管式固体电解质CO_2传感器的静态特性

Static characteristic of small hollow pipe-type solid-electrolyte CO_2 sensor

改变了传统的平面型固体电解质CO2传感器结构,采用管式结构的Al2O3为衬底,以溶胶-凝胶法合成的NASICON(Na快离子导体)材料为导电介质,制备出了新型小型空心管式传感器。与平面型传感器相比,管式结构具有加热效果好、功耗低、体积小等优点。重点考察了传感器的灵敏度、响应恢复、稳定性等传感器的静态特性。

?The structure of conventional planartype solidelectrolyte CO2 sensor was reformed.And a new small hollow pipetype sensor was fabricated,which was based on NASICON (Na superionic conductor) material synthesized by solgel process by using pipetype Al2O3 as substrate.Compared with the planartype device,the pipetype sensor possessed extra merit such as better heating efficiency,lower power consumption and more miniature framework.Some static characteristics of CO2 sensor including sensitivity,response and recovery time and stability were investigated in emphasis.
