Prediction of glass formability from liquid properties

TL;DR

This paper introduces a new formula to predict glass formability using only liquid properties, emphasizing the role of structural similarity between liquids and crystals, advancing the understanding without needing to produce the glass first.

Contribution

A novel prediction formula based solely on liquid properties is proposed, highlighting the importance of liquid-crystal structural similarity in glass formability.

Findings

Structural similarity influences glass formability.

Prediction formula works without prior glass formation.

Liquid properties alone can predict glass-forming ability.

Abstract

Glass formation is one of the most interesting phenomena in the condensed matter field. Considerable effort has gone into understanding and predicting the glass formability. However, the previous prediction requires the glass first made before the prediction can be performed. Here, we propose a new prediction formula using liquid properties only. Moreover, we demonstrated that the similarity between liquid and crystalline structure plays an important role in determine the glass formability. Previously, only the kinetics of nucleation and growth processes have been considered.
