在673-1123K温度范围内，研究了未掺杂和1mol%锶掺杂的LaP3O9玻璃和微晶玻璃的电导性能，这两种材料在玻璃态下都表现出较低的电导率。然而，当热处理温度高于晶化温度时，掺锶LaP3O9玻璃的电导率显著提高，而未掺杂LaP3O9玻璃的电导率即使在热处理后也没有提高。结果表明，掺锶LaP3O9玻璃的析晶诱导了质子导电，从而提高了玻璃的电导率。掺锶LaP3O9微晶玻璃的导电性能与烧结的掺锶LaP3O9微晶玻璃基本相似。
Electrical conduction properties of undoped and 1 mol% Sr-doped LaP3O9 glasses and glass–ceramics were investigated over the temperature range of 673–1123 K. Both the materials showed relatively low conductivities in the glassy state. However, the conductivity of the Sr-doped LaP3O9 glass significantly increased with a heat treatment above the crystallization temperature, while the conductivity of the undoped LaP3O9 glass did not improve even after the heat treatment. It was concluded that crystallization of the Sr-doped LaP3O9 glass induced protonic conduction and thus enhanced the conductivity. Electrical conduction properties of the Sr-doped LaP3O9 glass–ceramic fundamentally resembled those of the sintered crystalline Sr-doped LaP3O9.
