【摘要】 利用吸收光谱和Ｘ射线粉末衍射，对ＬｉＮｂＯ＿３晶体在Ｌｉ２＿ＣＯ＿３粉末中的还原过程进行了分析和研究，认为其中Ｌｉ￣＋离子在晶格中的扩散迁移是造成还原过程发生的一个重要因素。由此导致的可能的吸收光谱和晶格常数的变化，与实验结果完全符合。更多还原

【Abstract】 The reductive process of LiNbO₃ crystal in powdered Li₂CO₃ has been investigated by using absorption spectra and X-ray diffraction. An important factor in this process is that Li - ions diffusion and migration from host crystal.The possible changes in absorption spectra and lat- tice constants resulted from reduction completely conform to the experimental results.更多还原
