蓬莱出土古代青铜器锈蚀产物的显微喇曼光谱分析

A Raman Microscopic Study of the Patinas on Ancient Bronzes Excavated from Penglai City

首次运用显微喇曼光谱(RM)技术,对山东省蓬莱市登州博物馆馆藏古代青铜器的锈蚀产物进行分析,发现锈蚀产物的成分比较复杂,主要有蓝铜矿、孔雀石、氯铜矿、副氯铜矿、白铅矿、黄铅矾及方解石。证实该馆多数青铜器上白绿色粉状锈蚀产物为氯铜矿及副氯铜矿的混合物,是引发“青铜病”的重要隐患,所以,对这批青铜器进行科学的保护处理迫在眉睫。

For the first time, a Raman microscopic investigation of the patinas grown on the beautifully shaped bronzes collected in the Dengzhou Museum, Penglai City, Shandong Province, was done. The analyses results showed the diversity of patinas, and the pale greenish color found on almost half of the bronzes in the museum was proved to be the mixture of atacamite and paratacamite, both of which were thought might be dangerous to the stability of the bronzes and gave rise to ＂Bronze Disease＂. So their existence reflects a urgently necessity of treatment and conservation processes to these artifacts.
