We have constructed a gas sensor of SnO₂ equipped with ceramic electrodes and a heater made of CaCu₃Ru₄O, which demonstrated good device performance at high temperature. The CaCu₃Ru₄O-based electrodes and heater were formed on Al₂O₃ substrates using a screen-printing process, which is cost-effective and suitable for mass-production. This all-ceramic device reached 600 °C at the lowest, and remained intact after one week of operation at 500 °C and rapid thermal cycling of 500 °C temperature changes within 10 s. We propose CaCu₃Ru₄O as a robust and reliable conducting material that can be a substitute for Pt in various devices.
我们构建了一种配备陶瓷电极和由CaCu₃Ru₄O制成的加热器的SnO₂气体传感器,该传感器在高温下表现出良好的器件性能。基于CaCu₃Ru₄O的电极和加热器通过丝网印刷工艺形成在Al₂O₃衬底上,该工艺具有成本效益且适合大规模生产。这种全陶瓷器件最低可达600℃,在500℃运行一周以及在10秒内进行500℃温度变化的快速热循环后仍保持完好。我们提出CaCu₃Ru₄O作为一种坚固可靠的导电材料,可在各种器件中替代Pt。
