利用宝石显微镜、折射仪、静水称重法、红外光谱仪、X射线粉晶衍射仪、紫外-可见分光光度计及X射线能谱仪对一种产出广西并声称黑色软玉的玉石进行相关测试,结果显示:样品外观呈黑色,油脂-玻璃光泽,放大检查为纤维交织结构,折射率1.63(点测),相对密度3.15~3.20之间,红外光谱显示为阳起石相近,通过X射线粉晶衍射仪测试得出,该黑色样品的矿物主要成分为铁阳起石。
Using a gem microscope, refractometer, hydrostatic weighing method, infrared spectroscopy, X-ray powder diffraction, UV-visible spectrophotometer and X-ray spectrometer to produce a Guangxi and claimed to be black nephrite jade related tests The results showed that the sample showed a black appearance and an oil-glass luster. The sample was magnified and examined for fiber intertwined structure. The refractive index was 1.63 (spot measurement) and the relative density was 3.15-3.20. Crystal diffractometer test shows that the main component of the black sample is iron-actinite.
