Ionic conductivity of NaCl whiskers

Ионная проводимость нитевидных кристаллов NaCl

  • Published:
Acta Physica Academiae Scientiarum Hungaricae

Abstract

Direct current ionic conductivity of NaCl whiskers in the temperature range from 150 to 600°C has been studied. The thickness of the whiskers ranged from 4 to 50 μm in the tests. Activation energy values have been determined in intrinsic, extrinsic and association regions. Whiskers grown from a solution have been found to incorporate little impurity. Annealing in air has been demonstrated to affect ionic conductivity of NaCl whiskers.

Резюме

В работе исследовалась ионная электропроводность нитевидных кристаллов NaCl в области температур 150–600°C. Толщина исследованных нитевидных кристаллов равнялась 4–50 мк. Определены значения энергии активации в собственной, примесной и ассоциационной областях проводимости. Найдено, что только незначительное количество двухвалентных катионных примесей входит в нитевидные кристаллы, выращенные из водного раствора. Показано, что отжиг на воздухе сильно влияет на ионную электропроводность нитевидных кристаллов NaCl.
