| Abstract: | The influence of additions of 0, 2, 3.5, and 5% LiF on the sintering kinetics of MgF2 were studied using microcylindrical samples on a hot-stage microscope. The sintering rate of MgF2 was markedly enhanced, doubling at 650°C when the LiF was increased from 3.5 to 5 mol%. An approximate model is suggested explaining the observed sintering enhancement based on the increased concentration of fluorine ion vacancies. |
