Copper-Conducting Nasicon-Type CuTi2(PO4)3 Glass-Ceramics for Application to a Novel O2 Sensor
Published online by Cambridge University Press: 15 February 2011
Abstract
Fast Cu+-conducting ceramics containing NASICON-type CuTi2(PO4)3 and Cu3 (PO4)2 phases, which three-dimensionally interlock with each other, has been successfully prepared by the controlled crystallization of glass in the Cu-Ti-P-O system. The electrical conductivity of the glass-ceramic was ∼3×10−4Scm−1 at 300°C. The obtained glass-ceramics was applied to an oxygen-concentration cell operating at low temperature such as 100°C. The electromotive force (EMF) of the sensor showed good Nemstian response. The mechanism for O2 sensing is discussed in terms of the redox reaction between Cu+ ion in the dense glass-ceramic and O2 gas.
