摘 要: 利用X射线衍射(XRD)、傅里叶红外光谱(FTIR)、能量色散X射线荧光(EDXRF)、拉曼光谱(RS)等方法,对3块不同时代、不同埋藏环境铅釉陶表面腐蚀物的化学组成、物相结构进行了分析测试。结果表明,汉代釉陶表面的腐蚀物主要为白铅矿;宋代绿釉陶表面的腐蚀物主要为磷酸铅钙,锈蚀物中黄色是缘自其中一定量氧化铁的存在;唐三彩表面的腐蚀物中有磷酸铅钙与白铅矿两种物相结构的存在,锈蚀物表面的棕褐色是少量氧化铁与炭黑共同致色的结果。 In the present paper, different corrosions of three pieces of Chinese ancient lead glazed potteries from different burial circumstances were analyzed by using XRD, FTIR, EDXRF, RS etc, and the analyses indicate that the main crystalline phase of corrosion of HYT is cerussite (PbCO3), that of SYT is calcium-lead hydroxyapatite [Pb10-xCax (PO4) (OH)2 (x〈2.7)1 and the yellow area of the erosion is attributed to a certain mount of iron oxide, that of TSC is the cerussite (PbCO3) and calcium-lead hydroxyapatite [Pb10-xCax (PO4) (OH)2 (x〈2.7)1, and the brown-black area of the erosion product is the result of the existence of little mount of iron and carbon black.
