摘要
本文利用能量色散X射线荧光分析(Energy dispersive x-ray fluorescence:EDXRF)方法对产于和田的三种常见玉料进行了无损定性、半定量元素分析.结果表明,三种和田玉样品中都有含量较多的Mg,Ca,Si,O等元素以及微量的Al,K,Mn,S,Zn,Fe,Cu等元素.其中样品质量高、油脂性好的白玉和羊脂玉所包含的碳元素浓度较高,分别为24.545%和54.216%,而青玉中没有检测到碳元素.因此和田玉中碳元素的含量也许可以成为鉴别和田玉产品质量的一个标志性参数,对确定软玉的种类具有较好的参考意义.
Three kinds of usual Hotan jade have been studied with non-destructive energy dispersive x-ray fluorescence （EDXRF） technique qualitatively and semiquantitatively. All of them have large amount of Mg, Ca, Si, C, O and small amount of Al, K, Mn, S, Zn, Fe, Cu.The high quality white jade and the mutton fat jade with good grease have higher carbon content up to 24.545% and 54.216%, respectively, whereas the carbon content in sapphire is too low to measure. This indicates that the carbon content may be used for identifying the quality of Hotan jade, and it will be an important symbolic parameter in verifying the species of soft jade.
