采用电晕放电（CDT）方法在H2气氛下对25 NaO 1/2- 6LaO 3/2- 6 GeO 2 - 63 PO 5/2（mol%）玻璃中的钠离子进行质子置换。在CDT过程中，钠离子对质子的置换是从阳极侧向阴极侧进行的，电流恒定。在CDT 96小时后，获得0.3mm厚的无结晶透明玻璃板。从钠离子到质子的最大减少率为78 ± 10%。在400 °C时，质子传导率达到8.5 × 10−4S/cm。
Sodium ions in 25NaO1/2-6LaO3/2-6GeO2-63PO5/2(mol%) glasses were substituted with protons using corona discharge treatment (CDT) under a H2atmosphere. The substitution of sodium ion to proton proceeded from the anode side to the cathode side with constant current flow during the CDT. A crystalline free and transparent glass plate of 0.3 mm thickness was obtained after CDT for 96 h. The maximum decrease rate from sodium ion to proton was 78 ± 10%. The proton conductivity of 8.5 × 10−4S/cm was attained at 400 °C.
