出土青铜器是否带有原生“粉状锈”的探讨

“粉状锈”是一种危害性极强的锈蚀产物,本工作从铜的氯化物的生成和土壤环境两个方面入手,对其生成机理进行研究。研究结果表明,“粉状锈”并不是铜器在埋藏环境中直接形成的,而是在土壤中形成“病灶”———氯铜矿、氯化亚铜或两者的混合物放置于大气环境中逐渐转化而成。

An investigation of the origin of powdery rust of excavated bronze

"Powdery rust" is a highly harmful rust product.This paper takes on "powdery rust" from two angles;the formation of copper chlorides and the soil environment.A research on the formation of copper chlorides was conducted.It is considered that "powdery rust" was not formed directly in a buried environment."Powdery rust" was gradually formed when nantokite and atacamite or the interaction of both come into contact with the atmospheric environment.
