Investigation of the mechanism of mercury removal from silver- amalgam alloy

Odanović Zoran, Đurđević M.

An investigation of silver dental amalgam decomposition and the mercury removal mechanism was performed. The decomposition process was analyzed during thermal treatment in the temperature interval from 400 °C to 850 °C and for times from 0.5 to 7.5 h. The chemical compositions of the silver dental amalgam alloy and the treated alloy were tested and microstructure analysis using optical and scanning electron microscopy was carried out. The phases were identified using energy disperse electron probe microanalysis. A mechanism for the mercury removal process from silver dental amalgam alloy is suggested.
