摘要
铌酸锂(LiNbO_3)晶体由于本身具有的优良性能在许多领域中都获得了广泛的应用.以LiOH·H_2O和Nb_2O_5为原料采用水热合成法成功地合成了铌酸锂多晶粉体,并采用FTIR谱、XRD谱和SEM对产物进行了表征.结果表明,采用水热合成法能够得到结晶完整的四方柱形LiNbO_3多晶粉体.同时考察了反应温度、晶化时间和Li源对水热合成产物的影响.
LiNbO_3 crystals were widely used in many fields because of their excellent ferric properties. In this work, LiNbO_3 powders were successfully prepared via a simple and convenient hydrothermal method with LiOH·H_2O and Nb_2O_5 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.
