摘要：

Dissolution of mercury from amalgams and some intermetallic compounds found in the amalgam structure, such as .gamma.1, .gamma.2, and .beta.1, was examined during one week of aging in 0.9% NaCl solution at 37.degree. C. The amount of mercury released from .gamma.1 (30.2 .mu.g/cm2) was at least 13 times that released from amalgam (0.5-2.2 .mu.g/cm2) and five times that released from .beta.1(5.7 .mu.g/cm2). .gamma.2 released the least amount of mercury (0.46 .mu.g/cm2). The study revealed that as high as 55% of the mercury ions liberated from the amalgams and the amalgam phases was adsorbed onto the walls of the vials in which the specimens were aged.
