摘要
从铌酸锂和钽酸锂晶体的结晶学数据出发,分析其结构特征和组成化学键的结合情况.对于这两个晶体的结晶学格位占有情况和阳离子的位移进行了理论上的分析.作者首次明确地给出了铌酸锂和钽酸锂晶体中与晶体组成有关的阳离子位移趋势.
Starting from the crystallographic data of lithium niobate and lithium tantalate crystals, structural characteristics and chemical bonding behaviors of both crystals are studied. The lattice sites and cation displacements are also investigated. For the first time, the changing tendency of the composition related cation-displacement of lithium niobate and lithium tantalate crystals is clearly presented in the current work.
