摘　　要：本文在１．１～５．５ＧＰａ压力、７５０～２０５０℃温度范围内通过对产物的ＸＲＤ分析得到了以非晶为原料时，纯硬玉翡翠ＮａＡｌＳｉ２Ｏ６和透辉石翡翠０．６ＮａＡｌＳｉ２Ｏ６－０．４ＣａＭｇＳｉ２Ｏ６的晶化区．经过对晶化区中不同Ｐ、Ｔ点产物的结晶度计算，将区域分成三个晶化子区，并对各子区中合成样品的硬度、微观结构、强度、颜色、透明性和稳定性等进行了研究．结果表明，在较高温度和压力的Ａ区产物具有高的结晶度、粗壮的线状微晶及高有序度的编织结构，对应着产物的高硬度、纯正的颜色及良好的透明度和稳定性，是宝石级翡翠的合成区．The crystalline regions of synthetic jadeite NaAlSi2O6 and 0.6NaAlSi2O6-0.4CaMgSi2O6 were obtained at pressure 1.1￣5.5GPa and temperature 750￣2050℃ by using high pressure quenching. According to crystalline degree of product synthesized at different pressure and temperature, the crystalline region was divided into three parts (A, B and C). The microstructure, stability and some mechanics properties of the products synthesized at part A, B and C were investigated. It is found that part A, in the region of higher pressure and temperature, is the gem jadeite synthesis region.
