Literature Data

The ternary system Ag-Au-Pd was investigated because of its importance for dental alloys with corrosion resistivity comparable to more expensive alloys with higher Au content. Alloys of these elements are also used in jewelry. Ag, Au and Pd are completely soluble in each other in both the molten and solid states (>900°C). The Ag-Au-Pd ternary system shows only two-phase equilibrium, L+(Pd,Au,Ag), but the effect of Ag additions to the ordered compounds Au₃Pd and AuPd₃ has not been studied. The presence of a continuous series of solid solutions in the ternary system was established from the X-ray work of [1946Kuz] and thermal analysis by [1946Nem] and [1977Mia].
