以Lukas程序优化计算了三个赝二元系(SiO_2—A1_2O_3,Al_2O_3—Nd_2O_3,SiO_2—Nd_2O_3)的相图,得出了相应的热力学参数,并预测估算了赝三元系的等温截面和低共熔点。 1.热力学模型和计算
The phase diagrams of three pseudo-binary systems (SiO_2-A1_2O_3, Al_2O_3-Nd_2O_3, SiO_2-Nd_2O_3) were calculated by the Lukas program and the corresponding thermodynamic parameters were obtained. The isothermal cross sections and low Common melting point. 1. Thermodynamic models and calculations
