Abstract

Topological constraint theory has emerged as a rapid, predictive method to quantify the relationship between structural rigidity and glass properties. Understanding the structure of telluro-vanadate (TeO₂–V₂O₅) glasses has remained difficult owing to their complex mixture of structural units. Here, we propose a topological model that accurately captures the glass structure and can be used to predict properties such as glass transition temperature and hardness. The experimentally obtained properties are in agreement with predicted properties by the model suggesting that this simplified structural model accurately describes the V₂O₅–TeO₂ structure.

改性碲钒玻璃的拓扑约束模型

拓扑约束理论是量化结构刚性与玻璃特性之间关系的一种快速预测方法。由于碲钒酸盐（TeO2-V2O5）玻璃的结构单元混杂复杂，因此理解其结构仍然十分困难。在此，我们提出了一种拓扑模型，它能准确捕捉玻璃结构，并可用于预测玻璃转化温度和硬度等特性。实验获得的特性与模型预测的特性一致，表明这一简化结构模型准确地描述了 V2O5-TeO2 结构。

期刊介绍： The International Journal of Applied Glass Science (IJAGS) endeavors to be an indispensable source of information dealing with the application of glass science and engineering across the entire materials spectrum. Through the solicitation, editing, and publishing of cutting-edge peer-reviewed papers, IJAGS will be a highly respected and enduring chronicle of major advances in applied glass science throughout this century. It will be of critical value to the work of scientists, engineers, educators, students, and organizations involved in the research, manufacture and utilization of the material glass. Guided by an International Advisory Board, IJAGS will focus on topical issue themes that broadly encompass the advanced description, application, modeling, manufacture, and experimental investigation of glass.
