Diffusion of electronic defects in calcia-stabilized zirconia from a desorption rate study

Diffusion of electronic defects in calcia-stabilized zirconia from a desorption rate study

Diffusion coeff. for electronic defects in CSZ was independent of O sub 2 pressure but inversely proportional to Fe impurity concentration. Hole trapping by Fe impurity led to sluggish sensor response.
