金珍珠是南洋珍珠中的珍品,是一种天然有机宝石。采用红外光谱仪、拉曼光谱仪对购自市场的金珍珠进行了无损测试,并采用红外光谱粉末KBr压片、X射线粉晶衍射破坏性方法,与文石、方解石、文石和方解石粉末按不同配比的混合物进行比对测试。结果显示,金珍珠中的CaCO3是以文石相存在的,不含方解石。但是,可能因其有机成因或因有机物的影响,红外光谱、拉曼光谱与文石相比,具有一定的差异。
Gold pearl is a treasure in the South Sea pearls, is a natural organic gem. Using infrared spectroscopy, Raman spectroscopy on the gold pearl market nondestructive testing, and the use of infrared spectral powder KBr tablet, X-ray powder diffraction destructive method, and aragonite, calcite, aragonite and calcite powder according to different Than the mixture for comparison test. The results show that the gold pearl in the CaCO3 is aragonite exists, without calcite. However, it may be due to its organic cause or because of the influence of organic matter, infrared spectroscopy, Raman spectroscopy and aragonite compared to have some differences.
