Subsolidus solution and ionic conductivity of rock-salt structured Li3+5xTa1−xO4 electroceramics

Abstract: Lithium tantalate solid solution, Li3+5xTa1−xO4 was prepared by conventional solid-state reaction at 925 °C for 48 h. The XRD analysis confirmed that these materials crystallized in a monoclinic symmetry, space group C2/C and Z = 8, which was similar to the reported International Crystal Database (ICDD), No. 98-006-7675. The host structure, β-Li3TaO4 had a rock-salt structure with a cationic order of Li+:Ta5+ = 3:1 over the octahedral sites. A rather narrow subsolidus solution range, i.e. Li3+5xTa1−xO4 (0 ⩽ x … Show more

“…This blue shift reflects the interaction between the metal's atom and the OH group of the CH 2 OH moiety of celluose, resulting in the exhaustion of hydroxyl groups and consequent reduction in the intramolecular and intermolecular hydrogen bonds 68 , 69 . Regarding cellulose-Li structures, the Li–O bond stretching vibrations were found at 470–450 cm −1 70 73 and the intensity of such vibrations was found to increase with increasing the number of lithium atoms interacting with cellulose. The specific vibration of Na–O bond was found at 440–430 cm −1 in cellulose-Na structures 74 .…”
