Abstract

In addition to Sn‐rich corrosion products found in conventional amalgams, Cu‐rich amalgams also form Cu‐containing corrosion products. The nature of these Cu‐rich products was investigated by immersion of samples of 13 Cu‐rich amalgam systems in Ringer's solution for prolonged periods. SEM/EDS and x‐ray diffraction studies were used to identify the compounds formed and their morphology. Two products were identified: Cu~2~O, a red product, and CuCl~2~·3Cu(OH)~2~, a green product.
