摘　　要：以硅酸铝、硅酸钠为原料并加入少量一氧化锰作为致色剂制备出玻璃料,利用高温高压法确定了紫色硬玉质翡翠的最佳合成条件,并通过XRD、FTRS和SEM等方法对样品进行表征。实验结果表明:5.0 GPa、1450℃条件下合成样品的主要成分为NaAlSi2O6,样品呈现紫色,分子结构为硅氧四面体结构,具有柱状纤维编织形貌。我们的研究对于揭示天然翡翠的形成机制提供有力的参考。With Al2(SiO3)3 and Na2SiO3•9H2O as raw materials and adding a small amount of manganese oxide as reagent, the NaAlSi2O6 jadeite was synthesized by the method of high-pressure and high-temperature (HPHT). Amorphous glass materials are entirely converted to crystalline NaAlSi2O6 jadeite at 5.0 GPa and 1450˚C. All the experimental results reveal that the main components of the purple samples synthesized were NaAlSi2O6 and molecular structure was silicon oxygen tetrahedron structure, with columnar fiber woven morphology by XRD, FTRS and SEM. The research indicates that it will be help for deep understanding on the origin of natural jadeite.
