✦ Synopsis

The setting reaction of Ag,Sn amalgams may be thought of as a liquid phase sintering problem in which the reactants seek to form products with the lowest thermodynamic potential. We discuss the thermodynamic and kinetic considerations of this reaction. The lowering of free energy has been given as the rewon for the formation of the y l , y2, and PI phases and a qualitative reaction coordinate diagram has been hypothesized. The barrier height for the formation of the phase has been determined to be 137 kJ/mol.
