Abstract
The electrical and mechanical properties of hot-pressed versus sintered Li0.33La0.57TiO3 at temperature of 1050 °C were investigated. It was observed that hot-pressed Li0.33La0.57TiO3 exhibited a higher total Li-ion conductivity (∼20×) and hardness (∼11×) compared to sintered Li0.33La0.57TiO3 as a result of its higher density. Hot-pressed Li0.33La0.57TiO3 had a similar relative density and total Li-ion conductivity when compared to Li0.33La0.57TiO3 sintered at 1250 °C, where significant Li2O loss occurs. These results suggest that hot-pressing can be used as a consolidation method to reduce Li2O loss to obtain dense Li0.33La0.57TiO3.
