“华光礁Ⅰ号”沉船出水青白瓷表面沉积物的分析

Analysis of the concretion on the surface of the greenish white porcelain artifacts from Huaguang Reef Ⅰ

为探讨"华光礁Ⅰ号"沉船出水陶瓷器表面沉积物的成分及物相,以青白瓷为例,利用扫描电镜(SEM)和能谱仪(EDS)联用、X射线荧光(XRF)、X射线衍射分析(XRD)三种分析方法,对青白瓷表面不同颜色的沉积物进行了结构和化学组成的测试.结果表明,沉积物主要以碳酸盐类的文石、方解石以及含铁类的磁铁矿、针铁矿为主.本研究可为南海海域出水陶瓷器的保护提供参考和借鉴.

In order to determine the mineral composition of the concretion on the surface of the underwater porcelain from Huaguang Reef I wreck ship, taken greenish white porcelain as an example, the scanning electron microscope with energy-dispersive X-ray spectrometry （SEM- EDS）, energy-dispersive X-ray fluorescence analysis（XRF） and X-ray diffraction （XRD） were used to measure the structural and chemical compositions of different color concretion. The results indicate that the sample contained aragonite （CaCO3）, calcite, magnesian [（Ca, Mg） CO3], magnetite（Fe3O4）, and goethite[FeO（OH）].
