对一组燕国明刀币的化学成分和组织结构进行分析研究,可以获得有关古代金属矿、冶金、铸造技术等方面的信息。研究结果表明,燕明刀币合金中铅含量高,大部分为铅基青铜夹杂杂质及大量硫化物表明铜、铅的冶炼很可能采用了硫化物矿合金的分层现象是因缓慢冷却造成的。锈蚀主要是由于铅的优先腐蚀。 Analyzing and analyzing the chemical composition and organizational structure of a group of knives of Yan Guoming can get information on ancient metal mines, metallurgy and foundry techniques. The results show that the high content of lead in yanming knife-edge alloy, most of the lead-based bronze inclusions and a large number of sulfide shows that copper, lead smelting is likely to adopt a sulfide mineral alloy stratification is due to slow cooling . Corrosion is mainly due to the preferential corrosion of lead.
