Abstract

Corrosion products of amalgam produced in Ringer's solution were compared with products formed in vivo using scanning electron microscopy, X-ray microanalysis, and potentiostatic anodic polarization. The corrosion products in an old amalgam were probably a mixture of tin-oxide and tin oxychloride. In vitro corrosion of fresh amalgam resulted in the buildup of similar products.

摘要

使用扫描电子显微镜、X射线微分析和恒电位阳极极化法，将在林格氏溶液中产生的汞合金腐蚀产物与体内形成的产物进行了比较。旧汞合金中的腐蚀产物可能是氧化锡和氯氧化锡的混合物。新鲜汞合金的体外腐蚀导致了类似产物的积累。
