Effect of Sintering Time on the Purity and Morphology of LiTaO₃

Abstract:

Preparation of LiTaO3 was done using the sol-gel method which is also known as the wet chemical technique. Thermal analysis (TG-DSC) of LiTaO3 precursor was studied to determine an optimized heating temperature. LiTaO3 was heated at 550 °C with different sintering time of 12, 24, 48 and 72 h. The formation of pure LiTaO3 occurred during sintering time of 72 h which was confirmed using X-ray diffraction (XRD). The morphology of pure LiTaO3 was recorded using a Scanning Electron Microscope (SEM). Pure LiTaO3 can only be formed at a longer heating time in order to complete the oxidation process.
