摘要
用高温共焦显微激光 Raman光谱仪测定了不同温度下固体和熔融态的碳酸钠、碳酸锂以及不同成份的固态和液态 Li2 CO3- Na2 CO3混合物的 Raman光谱图 ,分析了 Na+和 Li+对碳酸根离子作用力的变化。根据 CO32 -对称伸缩振动模的波数移动情况 。
The Raman Spectra of solid and molten Na 2CO 3, Li 2CO 3, and some mixture of them have been measured with confocal high temperature Raman spectroscopic technique. The different effects of Na + and Li + to CO 3 2- ion were discussed. In according to the frequency shift of the symmetry stretch vibration mode of CO 3 2- ion, the mixing effect was also found in the solid mixtures.
