为了对“华光礁I号”沉船出水青白瓷表面白色和黄色凝结物进行了结构和化学组分的确定，通过利用扫描电镜(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，确认凝结物主要以碳酸盐类的文石、方解石为主。研究了不同的化学试剂对凝结物进行去除实验，对反应时间、浓度进行了分析，根据对陶瓷器损伤最低的原则，选择3%浓度的MA，5%浓度的DTPA和EDTA-2Na作为出水青白瓷器文物表面碳酸盐类凝结物的清洗去除试剂；本研究结果可为中国海洋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, using 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 structure and chemical composition of different color concretions. The results indicate that the sample contains aragonite (CaCO3), calcite and magnesian[(Ca,Mg)CO3].The removal experiment of concretion was carried out by using chemical reagents,and the reaction time and reaction concentration were analyzed. On the basis of little harm to porcelain, 3%malic acid (MA) and 5%diethylene triamine pentacetate acid (DTPA) and ethylene diamine tetraacetic acid disodium salt (EDTA-2Na) as chemical reagent were chosen to remove the concretion of greenish white porcelain. This work should be helpful to the conservation of underwater porcelain.
