Summary:A boundary of existence of solid solutions in the Li 8−2 x Mg x ZrO 6 system is found to be 7 mol % MgO. The transport properties of Li 8 − 2 x Mg x ZrO 6 solid solutions (the electronic component of total conductivity, the temperature and concentration dependences of conductivity and activation energy) are studied. It is supposed that, for Li 8 ZrO 6 phase and solid solution based on it, an abrupt change of conductivity in the temperature range from 663 to 713 K is caused by the transition of electrolyte into the superionic state.
