| Research Abstract |
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.
