合成硬玉玉石的矿物学研究

Study on Mineralogy of Synthetic Jadeite Jade Stone

通过X射线粉末衍射、偏光显微镜、电子探针、红外显微镜微区反射光谱、激光拉曼光谱等测试手段对几件绿色合成硬玉玉石样品进行仔细研究后发现,它是由结晶质和玻璃质物质组成,结晶质部分很少,结晶矿物为自形的长柱状硬玉,玻璃质物质的成分与硬玉的化学成分基本接近,但其w(SiO2)和w(Al2O3)明显偏高,而w(Na2O)明显偏低。合成硬玉玉石的结构比天然翡翠的要简单得多。

A few pieces of green synthetic jadeite jade stone are studied by using X-ray powder diffraction, polarizing microscope, EPMA, infared reflectance spectrum and laser Raman spectrum. The results show that the synthetic jadeite jade stone is composed of crystalline and glassy materials. The crystalline materials in a little amount are prismatic jadeite jade, and the compositions of glassy material are nearly correspond to that of jadeite and higher in w (SiO_2) and w (Al_2O_3) , lower in w (Na_2O). The textures of the synthetic jadeite jade stone are more simple than that of the natural jadeite jade.
