Microwave Processing for Improved Ionic Conductivity in Li2O-Al2O3-TiO2-P2O5 Glass-Ceramics

Li1.4Al0.4Ti1.6(PO4)3 (LATP) was synthesized using a glass‐ceramics approach through crystallization in a conventional box furnace and a modified microwave furnace. The microstructure of samples that were microwave processed at 1000°C showed a larger average grain size (0.87 μm) when compared with t...

Zusammenfassung:Li1.4Al0.4Ti1.6(PO4)3 (LATP) was synthesized using a glass‐ceramics approach through crystallization in a conventional box furnace and a modified microwave furnace. The microstructure of samples that were microwave processed at 1000°C showed a larger average grain size (0.87 μm) when compared with the grain size of conventionally processed samples (0.30 μm) at the same temperature. Microwave processing led to significant enhancement of the conductivity when compared with conventional processing for all crystallization temperatures investigated. The highest total conductivity achieved was of glass microwave processed at 1000°C, with a conductivity of 5.33 × 10−4 S/cm. This conductivity was five times higher than that of LATP crystallized conventionally at the same temperature.
