Electrical conductivity of hexagonal Ba(Ti0.94Ga0.06)O2.97 ceramics

Impedance spectroscopy is used to estimate the bulk conductivity, sigma b, of hexagonal (6H)-Ba(Ti0.94Ga0.06)O2.97 ceramics in air, N2 and 5% H2/95% N2 between 400 and 1000 C. Isothermal plots of log sigma b vs log pO2 in the temperature range between 700 and 1000 C show the presence of a p-n transi...
