Abstract: The interrelationship between the structure, phase composition, and transport characteristics of solid electrolytes based on ZrO$_2$ has been studied as dependent on the content of stabilizing Y$_{2}$O$_{3}$ additive. It is established that twin boundaries do not lead to the appearance of additional mechanism of ionic conductivity acceleration in ZrO$_2$–Y$_{2}$O$_{3}$ crystals. The maximum conductivity has been observed in ZrO$_2$–(8–10) mol % Y$_{2}$O$_{3}$ crystals containing a $t''$ phase, in which oxygen atoms are displaced from high-symmetry positions characteristic of the cubic phase.
