Electric Conductivity of Lithium Metazirconate

Lithium metazirconate Li2ZrO3 was synthesized by various methods, and its electric conductivity was studied in the range 300–600°C. For the sample obtained by solid-phase synthesis, the temperature dependence of conductivity is linear in the Arrhenius coordinates and coincides with the literature data for Li2ZrO3 obtained by the similar procedure. The sample synthesized and sintered in vacuum has higher electric conductivity, but contains a Li2CO3 impurity. Possible reasons for the abrupt change in the conductivity of Li2ZrO3 at 430–470°C reported in some works were considered.
