The Gibbs Energy Description of Nd∶YAG System

摘要：

　　Sublattice model is used to describe the complex system,Neodymium-doped yttrium aluminum garnet (Nd∶YAG),and then Gibbs energy function of Nd∶YAG system is seriously evaluated,mainly focusing on the instability of NAG,which has a direct effect on the Gibbs energy of NAG as well as Nd∶YAG.Incorporating the selected literature thermochemical data of Nd∶YAG system with the reevaluated parameters in Gibbs energy function according to a method utilized for defining the instability of NAG,the Gibbs energy function is well described.Trying to be more convincible,the method utilized for defining compounds stability and reevaluating the parameters has been test in Al2O3-Nd2O3,Al2O3-Y2O3,Al2O3-Gd2O3,Al2O3-Sm2O3 systems,achieving a satisfying agreement.
