Trial of an All-Ceramic SnO(2) Gas Sensor Equipped with CaCu(3)Ru(4)O(12) Heater and Electrode

We have constructed a gas sensor of SnO(2) equipped with ceramic electrodes and a heater made of CaCu(3)Ru(4)O(12), which demonstrated good device performance at high temperature. The CaCu(3)Ru(4)O(12)-based electrodes and heater were formed on Al(2)O(3) substrates using a screen-printing process, w...

Sumario:We have constructed a gas sensor of SnO(2) equipped with ceramic electrodes and a heater made of CaCu(3)Ru(4)O(12), which demonstrated good device performance at high temperature. The CaCu(3)Ru(4)O(12)-based electrodes and heater were formed on Al(2)O(3) 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 CaCu(3)Ru(4)O(12) as a robust and reliable conducting material that can be a substitute for Pt in various devices.
