Abstract
Electrical conductivity was applied to monitor isothermal equilibration kinetics for undoped BaTiO3 single crystal within p-type regime at 1205 K during an oxidation experiment. Chemical diffusion coefficient in BaTiO3 was determined using two different analytical solutions of the Flick's second law involving a parabolic equation and a logarithmic equation. A very good agreement between the diffusion coefficients obtained using these equations (1.249x10-5 and 1.29x10-5 cm2s-1, respectively) was revealed.
