| 摘 要： | 根除或有效控制有害的“粉状锈”是青铜器保护的关键技术。根据铜的氯化物在一定温度下易分解或挥发这一性质，本文利用热分析仪和X射线衍射（XRD）手段，对青铜试样表面生成的碱式氯化铜（Cu2Cl(OH)3）及氯化亚铜（CuCl）试剂粉末进行分析。结果表明，在大气环境中加热到350℃即可使氯铜矿分解，消除Cl-；CuCl在420℃~430℃融化并挥发，在600℃挥发急剧加速，实验条件下至789℃已完全挥发。

| Abstract: | The key technology of bronze protection is to control and exterminate the harmful "powdery rust". Based on the character that copper chloride is easy to decompose and volatilize,this paper analyzed Cu2（OH）3Cl made from the surface of bronze samples and CuCl using thermal analyzer and X-ray diffraction（XRD）.The results showed that the Cl- can be outrooted if copper chloride ore were heated up to 350°C in the air.Besides, CuCl volatilized easily and the reaction accelerated at 600℃and finished at 789°C |
