The setting reaction of Ag3Sn 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 reason for the formation of the gamma1, gamma2,and beta1 phases and a qualitative reaction coordinate diagram has been hypothesized. The barrier height for the formation of the beta1 phase has been determined to be 137 kJ/mol.
Ag3Sn汞合金的凝固反应可被视为一个液相烧结问题，其中反应物试图形成具有最低热力学势的产物。我们讨论了该反应的热力学和动力学因素。自由能的降低被认为是γ1、γ2和β1相形成的原因，并假设了一个定性的反应坐标图。已确定β1相形成的势垒高度为137 kJ/mol。
