The ε-Cu₃Sn, η/η′-Cu₆Sn₅, Al₃Ni and Al₃Ni₂ intermetallics have been produced as pure phases by the mushy zone resolidification in a temperature gradient. Powder XRD and SEM/EDX analysis were used for sample characterization. Heat capacity measurements have been performed in temperature ranges starting from 210 K up to temperatures close to the stability limits of the investigated phases. Based on the experimental results, the specific heat capacities of the intermetallics have been described from 0 K using an extended Einstein model. The model was chosen as one of most promising models for describing heat capacities for the 3^rd generation of CALPHAD type thermodynamic databases and as it allows the determination of the standard entropies of intermetallic compounds.

ε-Cu ₃ Sn、η/η'-Cu ₆ Sn ₅、Al ₃ Ni 和Al ₃ Ni ₂金属间化合物已通过糊状区在温度梯度中的再凝固而作为纯相产生。粉末 XRD 和 SEM/EDX 分析用于样品表征。热容量测量已在从 210 K 到接近所研究相的稳定性极限的温度范围内进行。根据实验结果，使用扩展的爱因斯坦模型从 0 K 开始描述金属间化合物的比热容。该模型被选为最有前途的车型之一是为了讲述3热容量^RD CALPHAD 类型热力学数据库的生成，因为它允许确定金属间化合物的标准熵。
