The corrosion pattern of dental amalgam in aqueous media was interpreted theoretically by means of log(ai/a(ref))-pe diagrams. The definitions on which the diagrams were based were given, and their features were described. All sparingly soluble compounds which were expected to be formed in reactions with the solvents considered were listed. All the corrosion products reported in the current literature were found to be formed, and the conditions for their formation were established. It emerged that it was necessary to exclude other sparingly soluble compounds with theoretically might be formed. Two compounds, CuSCN and AgSCN, which have not been reported previously were found to be possible corrosion products. Corrosion products containing mercury compound cannot be formed on amalgam restorations with no metallic contact with other materials.
通过log(ai/a(ref))-pe图从理论上解释了牙科汞合金在水介质中的腐蚀模式。给出了该图所依据的定义，并描述了其特征。列出了预期在与所考虑的溶剂反应中形成的所有微溶化合物。发现当前文献中报道的所有腐蚀产物均已形成，并确定了其形成条件。结果表明，有必要排除理论上可能形成的其他微溶化合物。发现两种以前未报道过的化合物CuSCN和AgSCN可能是腐蚀产物。在与其他材料无金属接触的汞合金修复体上不会形成含汞化合物的腐蚀产物。
