| 摘 要： | 通过对来自新疆、云南、广西、内蒙古、越南和南非等地电气石的化学成分、X射线衍射的物相分析和晶格常数的测定,研究了电气石的化学成分和晶格常数的关系.分析认为,阳离子质量浓度与离子半径是影响电气石晶格常数的主要因素;Fe和Mg元素对电气石晶格常数有较大影响;随Fe或Mg元素含量增加,晶格常数增大.不同种类电气石的晶格常数有较大差异,电气石的外观色泽与晶格常数对应关系良好.

| Abstract: | Based on the analysis of the chemical component,XRD phase and the test of the crystal lattice parameter of tourmaline from Xinjiang,Yunnan,Guangxi,Neimenggu,Vietnam and South Africa,the relationship between the chemical component of tourmaline and its crystal lattice parameter was studied.Results show that content of the cation and radius of the ion are the main factors that affect the crystal lattice parameter which augments with the increase of the content of Fe and Mg.Crystal lattice parameter of different tourmaline varies evidently.The crystal lattice parameter of the tourmaline affects its colour and luster. |
