Sintering temperature determining optimal

In this context. Fig. 16.9 reported by Jiao et al (2002) shows the typical experimental curve to determine the optimal working temperature at which to detect CO2 by means of BaTiOj-CuO sintered ceramics. The test is carried out at 5000 ppm of CO2 and the sensor sensitivity is defined by the author as Rgas/Rair.
