Tóm tắt

Protons were injected into glasses at high temperatures using anodes such as molten NH4HSO4, Pt in forming gas, and graphite in an atmosphere containing H2O vapor. Large electric fields develop near the anode surface of the glass and create an ion‐depleted region beneath the anode. The electrical conduction characteristics are attributed mainly to the motion of protons in the high‐field region. The ir absorption data indicate that injected protons exist in at least 3 bonding configurations in a proton‐exchanged region beneath the depleted region. The proton concentration in the exchanged region is estimated to be ∼80 to 95% of the Na concentration in the normal glass.
