Abstract : A previously unreported loss peak in polycrystalline CaF2 was observed by both dielectric loss and internal friction methods. Earlier investigators reported that O(--) and A1(3+) can each form different impurity vacancy pairs which cause Debye-type losses in CaF2. In this study the addition of sodium fluoride to CaF2 caused a loss peak at higher frequencies, for the same temperature, than other loss peaks reported.
