【Abstract】 The relationship between pseudoeuteetie regions and glass formation regions has been studied preliminarily in this paper. The opinion that pseudoeutectie regions may be the locations where the formation of glasses is relatively easy has been put forward by comparing the formation processes of pseudoeutectics with that of glasses. In this paper, a calculation method of the pseudoeuteetie regions using chemical potential has been developed, and the regions of some binary silicates and ternary ZnCl2-based halide systems have been calculated. It is found that under certain degrees of supercooling the pseudoeuteetie regions fit the glass formation regions under certain dynamic conditions well, and the sequence of their sizes is basically the same. Therefore, it can be predicted that the method by calculating pseudoe-ntectic regions can be used not only for the prediction of the positions of glass formation regions, but also for the comparison of different systems in glass formation abilities.更多还原
