Phase transitions in solid electrolytes on the base of Na-(β-β '')-alumina

It was observed the grate advance of temperature dependency electron conductivity in the range of low temperatures in pure Na (ƒ ƒ'') alumina, and in one doped by yttrium, copper, bismuth and lead. It is marked, that this phenomenon is observed in the same temperature range that the superionic transition observed in Na (ƒ ƒ'') alumina earlier by other authors. The grate advance of electron conductivity observed by us is analysed by us in the framework of а vibration conception.
