摘要
利用纳米技术和半导化技术，制备了ＣｕＯＢａＴｉＯ３ 复合氧化物电子陶瓷电容型ＣＯ２ 气敏元件，该元件可用于环境中ＣＯ２ 气体的监测．该元件在１２７ ～４７７ ℃范围，对ＣＯ２ 气体呈现较好的敏感特性；可测气体浓度范围０ ～９５ ％（ 体积分数，下同），在低浓度范围（０～５％ ）内，电容与浓度呈线性关系；能经受高浓度ＣＯ２ 气流的冲击，有较快的响应恢复速度；重现性和选择性较好；是一种很有发展前途的ＣＯ２ 气敏元件．
A novel gas sensitive element for detecting environmental CO 2 was developed. Nanometer and semiconductorization techniques were employed to prepare the CuO BaTiO 3 complex oxides used to manufacture electronic ceramic capacitance type sensitive element for detecting CO 2. Results show that the element possesses excellent CO 2 sensitivity in the temperature range 127～427 ℃. The detectable CO 2 concentration is 0～95%, and the capacitance measured varies linearly with the CO 2 concentration in the low concentration range(0～5%CO 2). Excellent selectivity, good repeatability, rapid responsibility and rapid recoverability are also observed.
