Abstract
Bulk and grain boundary diffusion of calcium in yttria fully stabilized zirconia was studied in air in the temperature range from 1100 to 1400 degrees C. Secondary ion mass spectrometry (SIMS) was used to determine the diffusion profiles as average concentration vs. depth in the B-type kinetic region. The obtained results allowed the calculation of the temperature dependence of the bulk diffusion coefficient D and the grain boundary diffusion parameter D'delta s. Activation energies of these processes amount to 333 and 367 kJ mol(-1), respectively. Diffusion data of calcium were compared to those of titanium obtained previously using the same zirconia material.
