Study on the evolution of super-protonic conduction in phosphate glasses

本文研究了磷酸盐玻璃超质子导电的起源。通过低温熔融或在低于玻璃化转变温度的潮湿气氛中退火合成的玻璃获得高质子传导。据认为，高质子传导性是由质子经由在熔融或退火期间并入玻璃中的水分子跳跃引起的。同时还制定了制备同时具有高质子传导性和化学耐久性的玻璃的指南。

The origin of super-protonic conduction in phosphate glasses has been investigated. High proton conduction was obtained in glasses synthesized by low-temperature melting or by annealing in humid atmosphere below the glass transition temperature. It is considered that the high proton conduction is caused by proton hopping via water molecules incorporated in the glass during melting or annealing. The guide to the preparation of glasses compatible with both high proton conduction and chemical durability was also developed.
