摘　　要：采用高温固相法、溶胶-凝胶法制备了NASICON固体电解质材料,并利用XRD、IR、Raman、SEM等现代分析手段对NASICON材料进行了分析表征,优选出NASICON材料制备的工艺条件。对制备不同检测气体所需的敏感电极材料组份及制备方法进行了比较系统的研究。并以NASICON为离子导电层,以BaCO_3-Li_2CO_3、Na_2SO_4-Li_2SO_4等复合盐以及单一或复合金属氧化物为敏感电极材料,制作出了具有良好性能的CO_2、CO、SO_2、NO_2、H_2S、Cl_2、NH_3等分立器件和集成一体化的CO-C_7H_8(甲苯)、NH_3-C_7H_8两种双功能器件。NASICON solid electrolyte materials were synthesized by solid-state reaction, sol-gel method and were analyzed by XRD, IR, Raman, SEM. Also the optimal process conditions were selected. The component and preparation method of the sensing materials which were sensitive to different gases were systemic studied. Discrete devices （CO2, CO, S02, NO2, H2S, Cl2, NH3） and two difimctiona] devices （CO -C7H8 （toluene） , NH3 -C7 H8 ） with well sensing characterietics were prepared with NASICON as the ionic conductive layer, compound salts （BaCO3 -Li2CO3, Na2SO4 -Li2SO4 ） and single or compound metal oxides as the sensing materials.
