本文以Mandarino或作者给定的K值为基础,计算了格拉斯顿-代尔离子折射度(即GDIR值)。并对离子的电子壳层结构对矿物折射性质的影响作了讨论,得出了如下结论: 1.氖型结构离子的化合物折射率随其密度增加而线性地增加; 2.惰性气体型离子和18电子型离子的离子折射度有不同的变化规律; 3.周期表中ⅠA,ⅡA,ⅢA,ⅣA,ⅤA和ⅥA族的离子的折射度随原子序增加而线性地增加; 4.第一过渡族元素的离子折射度有双驼峰型的曲线; 5.由于镧系的收缩,稀土元素的离子折射度随原子序的增加而降低。
Based on the K value given by Mandarino or the author, the Gladstone-Dir ion refraction (ie, GDIR value) is calculated. The effects of the electron shell structure on the refractive properties of minerals are discussed. The main conclusions are drawn as follows: 1. The refractive index of neon-type ionic compounds increases linearly with the increase of their density. 2. The inert gas ions and 18 ionic ions have different ion refractive index changes; 3. Periodic Table IA, IIA, IIIA, IVA, VA and VIA ions of the refractive index increases linearly with the atomic order; 4. The first transition There is a double hump type curve for the ionic refractive index of the family elements. 5. The refractive index of the rare earth elements decreases with the increase of the atomic number due to the shrinkage of the lanthanides.
