二元玻璃系统的混合热力学与分相边界的预测

Prediction of Immiscibility Boundaries of Binary Glass System

根据对新的玻璃网络组体的假设,推导并建立了二元氧化物玻璃系统的不混溶边界的关系方程,并对部分玻璃系统的不混溶边界作了预测,并与实验结果进行了比较.结果表明,理论预测与实际结果相符得很好.根据该理论计算了玻璃网络形成分子与金属氧化物之间的相互作用能.新得出的理论首次从理论上解决了二元氧化物玻璃体系中不混溶边界的非对称曲线问题.

The assumption of molecules group of glass network was made, and the relation of immiscibility boundary was derived and established. The immiscibility boundary curve of some glass system was calculated and estimated by using the new theory relation, and the results are closely agreed with the experimental immiscibility boundaries. This relation first solved the non-symmetry curve of immiscibility for the binary oxides glass system theoretically. It can be considered that this new theory and the equation can be applied in the more glass phase separation systems, and mutual interaction between different molecules can be calculated further.
