中文摘要：

模拟天然翡翠成矿原理,采用优化的合成工艺,在高温高压下将非晶质的翡翠成分粉末转化为晶态翡翠,部分合成翡翠的质地温润细腻、色泽均匀,具有高档翡翠的品质。X射线衍射（XRD）物相分析和扫描电镜（SEM）显微分析结果表明：合成样品结晶矿物为硬玉,且结晶程度较好,晶粒细密,编织致密有序。拉曼光谱显示,合成翡翠的拉曼特征峰位与天然翡翠一致,且谱线尖锐,表明其结晶程度高。合成翡翠的硬度、密度和热稳定性等常规宝玉石参数也与天然翡翠接近。研究发现,在实验所采用的温度、压力范围内,温度对合成翡翠晶粒的生长和编织情况有很大的影响。

英文摘要：

Well-crystallized jadeite was successfully synthesized from its glass phase under high pres- sure and high temperature conditions by simulating the mineralization principle of natural jadeite. Some of the synthetic jadeite samples present highly saturated colors and smooth finish which are the main features of high quality jadeite. The results of X-ray diffraction （XRD） and scanning electron microscopy （SEM） characterization show that the jadeite samples possess a relatively high degree of crystallinity and exhibit a good texture structure with vitreous luster and an appearance exactly like those of natural jadeite. The jade samples were also studied in detail by confocal micro-Raman spec- troscopy. It is observed that the sharp Raman bands of synthetic jadeite samples are consistent with those of the natural jadeite. The differential scanning calorimetry （DSC） curve indicates that the ther- mal stability of synthetic jadeites is the same as natural jadeite. The hardness and density of synthetic jadeite measured are also similar to natural jadeite. In addition,it is found that the temperature plays a quite important role in crystal growth and knitting structure in terms of the synthetic jadeite samples.
