| Abstract: | LiNbO3 crystals were widely used in many fields because of their excellent ferric properties. In this work, LiNbO3 powders were successfully prepared via a simple and convenient hydrothermal method with LiOH·H2O and Nb2O5 as the starting materials. FTIR spectra and XRD patterns of the as-prepared samples showed good crystalline and high purity. At the same time, the effects of different Li sources, crystallization temperature and time on the as-prepared product were also investigated. |
