Construction of databases on surface tension of multi-component liquid alloys and molten oxides

本课题“多组分液态合金和熔融氧化物表面张力数据库的建立”分三步进行。多组分熔融氧化物表面张力的测量：自制了最大泡压法实验装置，用于测量熔盐混合物和熔融氧化物混合物的表面张力。在这种方法中，我们还可以测量这些熔融混合物的密度。建立了多组分液态合金、熔盐混合物和氧化液混合物表面张力的热力学模型：为了应用一些最初用于计算各种热力学量和相图的热力学数据库，我们推导了多组分液态合金、熔盐混合物和氧化液混合物表面张力的热力学模型。将上述熔液表面张力的热力学模型与热力学数据库相结合：我们将上述熔液表面张力的热力学模型与热力学数据库相结合，构建了数据库系统，得到了上述实验结果以及多组分液态合金、熔盐混合物、熔氧化物混合物表面张力的计算结果。

We have proceeded the present project "Construction of databases on surface tension of multi-component liquid alloys and molten oxides" in the following three steps :[1].Measurement of surface tension of multi-component molten oxides :We have made the experimental apparatus of maximum bubblle pressure method to meaure the surface tension of molten salt mixtures and molten oxide mixtures. In this method, we could also measure the density of those molten mixtures.[2].Derivation of the thermodynamic model for the surface tension of multi-component liquid alloys and molten salt mixtures, and molten oxide mixtures :In order to apply some thermodynamic databases, which have been originally constructed to calculate various thermodunamic quantities and phase diagrams, we have derived the thermodynamic model for the surface tension of multi-component liquid alloys and molten salt mixtures, and molten oxide mixtures.[3].Combining the above thermodynamic mdels for the surface tension of molten mixtures with the thermodynamic databases :We have combined the above thermodynamic mdels for the surface tension of molten mixtures with the thermodynamic databases, and constructed the database system to get the above experimental results as well as the calcuated results of the surface tension of multi-component liquid alloys and molten salt mixtures, and molten oxide mixtures.
