Unformatted text preview: ile recognizing the uncertainty in the calculated intrinsic mobility due to the lack of definiGve data for the diffusion coefficient of the rate- controlling ion, trends in the mobility values are clear. §༊  First, the measured mobiliGes of the oxides are well below the calculated intrinsic values. §༊  Second, dense samples containing dopants or second- phase precipitates have low mobiliGes, while the mobiliGes for porous samples are much lower than those for the dense samples. §༊  Third, when liquid phases are present, the mobiliGes are higher than those for porous samples but oeen not much higher than for dense samples. 22 Mechanisms Controlling the Boundary Mobility q༇  While recognizing the uncertainty in the calculated intrinsic mobility due to the lack of definiGve data for the diffusion coefficient of the...
