采用金属醇盐水解法制备了快质子导电P2 O 5-ZrO 2 - 2SiO 2玻璃。通过在150至400 °C下加热获得的玻璃是化学稳定的，并且在室温下表现出1004 S/cm的高电导率，该电导率比不含P2 O 5的玻璃的电导率高1004个数量级。这些高电导率被认为是由与POH基团键合的分子水加速的快速质子转移。这些玻璃具有很高的实际应用潜力。
Fast proton-conducting P2O5–ZrO2–2SiO2 glasses were successfully prepared by the hydrolysis of metal alkoxides. The glasses obtained by heating at 150 to 400 °C are chemically stable and exhibit high conductivities of ∼104 S/cm at room temperature, conductivities that are higher by ∼4 order than that of glasses containing no P2O5. These high conductivities were regarded as the fast proton transfer accelerated by molecular water bonded with POH groups. These glasses have a high potential for practical applications.
