Comment on the following values of electrical conductivities: Na -alumina, 3 10 2 1 cm

Question:

Comment on the following values of electrical conductivities: Na β-alumina, 3 × 10⁻² Ω⁻¹ cm⁻¹(at 298 K); Li₃N, 5 × 10⁻³ Ω⁻¹ cm⁻¹ (at 298 K); NaCl, 10⁻¹⁵ Ω⁻¹ cm⁻¹ (at 300 K). Would you expect these values to be direction-independent with respect to the crystal under study?
