Mixed ionic-electronic conductivity and structural properties of strontium-borate glass containing nanocrystallites of Bi2 VO5.5
Abstract
Samples of strontium borate glass containing bismuth vanadate nanocrystallites were prepared. Nanocomposites containing up to 45mol% of the Bi2VO5.5 phase exhibit electrical properties closer to the strontium-borate glass than to the ferroelectric Bi2VO5.5 ceramic. The glass matrix still may contain some part of bismuth and vanadium ions even after crystallization process and there is too little of crystalline phase to observe its ferroelectric properties. The glass-ceramic nanocomposite containing 50mol% of Bi2VO5.5 phase exhibits electrical properties closer to the Bi2VO5.5 ferroelectric. The electric parameters of conduction processes in the Bi2VO5.5 nanocrystallites, glass matrix and phases boundaries are discussed. The conduction process mechanism in all nanocomposites for the low temperatures is mixed ionic–electronic and in the higher temperatures the oxygen ion hopping starts to dominate.
