Stability of A Determination of Intermediate Compound Standard Gibbs Free Energy of Formation
-
摘要: 本文從熱力學原理出發,推導出:二元系中化合物的標準生成自由能符合擬拋物線規則;推廣到三元系中則應符合拋物面規則;并且利用上述規則判定含稀土體系中化合物的穩定性。Abstract: Based on principles of thermodynamics, it is derived that: in a binary system, a quasi-parabola regulation must be obeyed by the standard Gibbs free energy of formation of compound. Extended to ternary systems, a quasi-paraboloid regulation also is done. The stabilities of intermediate compound in binary systems containing a rare earth element are criticized.
