Electrical conductivity of LiNbWO6

The electrical conductivity of polycrystalline LiNbWO₆, which has a trirutile structure, was studied by the ac impedance method and dc resistance measurement. From the results, the following is clear; LiNbWO₆ is a lithium ionic conductor, its electrical conductivity at 150°C is $\text{1.8 × 10}{}^{\mathrm{?6}}\text{Ω}{}^{\mathrm{?1}}\text{cm}{}^{\mathrm{?1}}$ and the electronic transference number is about 0.03.
