Description:
Compositions having the general formula BaTiO3-CuO+x wt% Ag, where x=0,1,1.5, and 2 have been prepared by solid state ceramic processing and sintered at 500 and 700∘C for 5 h. Thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), infrared absorption spectra (IR), and scanning electron microscopy (SEM) were used to characterize the obtained sensor pellets. It was found that no solid state reaction took place between BaTiO3 and CuO during sintering process. The sensitivity of the prepared sensors to CO2 gas increases with increasing sintering temperature and Ag content. The correlation between Ag content at different sintering temperature and structure characterization is discussed.
