摘要
采用甘氨酸-硝酸盐法合成了La2NixCu1-xO4（x=0～0．5）复合氧化物，制成了厚膜型元件，研究了烧结温度、膜厚、介质粉含量等对材料氧敏性能的影响。测试结果表明：700℃烧结、膜厚为80μm、介质粉含量为5％的厚膜型La2NixCu1-xO4的氧敏性能最优，400℃时的灵敏度可以达到7．1。
Perovskite-type oxide La2 Nix CU1-xO4 （x =0-0.5 ）is synthesized by the glycine-nitrates process （GNP）. The thick film type oxygen-sensing sensor is fabricated. The effect of sintering temperatures, thickness and the content of glass powders on the oxygen-sensing properties of the thick films is investigated. The results illustrate that thick film La2 Ni0.1Cu0.9O4 （5 % glass powder,80 μm thickness, sintering at 700 ℃ exhibits the best oxygen-sensing properties and has a maximum sensitivity of 7.1 at 400℃.
