摘要
模拟天然翡翠成矿的物理、化学条件,参照硬玉各元素的理论质量分数,选用合适的化学试剂配制合成翡翠原料,采用高温固相法制备非晶质的、具有翡翠成分的玻璃料,再利用高压固相转变的原理,在高温高压设备上对其进行结构转化处理,使其在翡翠稳定区内结晶。X射线粉末衍射、傅里叶变换红外光谱、偏光显微镜矿物结构的分析结果表明:合成样品中的主要结晶矿物为硬玉,其红外吸收光谱与天然翡翠的基本一致,部分样品的结构转化较完全,结晶程度较好,且其硬度、密度及折射率等常规宝石学参数也与天然翡翠的十分相近。
The study on the mechanism of the synthetic jadeite jade is carried out by using the solid translation with the chemical material at high pressure and high temperature. The synthetic samples got in the experiment are analysed by using X-ray powder diffraction, infrared spectrometer and polarizing microscope. The results show that the main crystal phase in the synthetic jadeite jade samples is jadeite, and the gemmological characteristics of the synthetic jadeite jade samples are very similar to that of the natural one.
