Ionic Conductivity of Calcium Fluoride Crystals
Abstract
Transference number measurements on pure and doped crystals show that the predominant defect in CaF2 crystals in the anti-Frenkel disorder type involving equal concentrations of negative ion vacancies and negative ion interstitials. The mobilities of the F— vacancy and F— interstitial have been determined by measuring the electrical conductivity of crystals doped with NaF and YF3. The activation energy for mobility of the vacancies varies from 20±1.5 kcal/mole at 200°C to 12±1 kcal/mole at 600°C. For the interstitials, the mobility in the range from 690 to 920°C is given by u=(1.34×107)T−1 exp[−(19±4)×103/T] cm2/sec volt.The number of anti-Frenkel defects in the pure crystal in the range from 640 to 920°C is given by n0=2.96×1025exp[−(16.3×103)/T] cm−3.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
