摘要：

Conductivity of CaF2-(20, 30, 40 vol %) MgO composites was measured as dependent on the temperature and MgO dispersion degree using a standard four-probe dc method. It is shown that the conductivity of composites grows at an increase in the MgO dispersion degree and volume fraction and achieves its maximum at 30 vol % MgO. It is found that the conductivity of CaF2-30 vol % MgO nanocomposite is higher by two orders of magnitude as compared to pure CaF2.
