Sol-Gel Derived LiNbO3: Its Crystallization Behavior Analyzed by High-Temperature X-Ray Diffraction Method

Download PDF

Abstract:

Here, we have examined the crystallization behavior of a sol-gel derived LiNbO3 precursor using a high-temperature X-ray diffraction (HT-XRD) method. LiOC2H5 and Nb (OC2H5)5 were used as starting alkoxides. High-temperature reaction behavior was analyzed by HT-XRD up to 1000°C in air on a Pt stage, as well as by thermogravimetry and differential thermal analysis up to 1100°C in air. HT-XRD, DTA-TG and SEM observation revealed that ~700°C was a favorable temperature to obtain fine and well-crystallized LiNbO3 crystals.
