摘要

本研究将硅酸盐玻璃和熔体的等温体积与其化学成分的合并离子体积联系起来。这种关系是对晶体氧化物、硅酸盐、铝硅酸盐和其他以 O2- 作为组成阴离子的材料已建立的关系的扩展。该关系提供了对键配位的约束，指出了熔体和玻璃中配位的压力诱导变化以及原子间距离，并量化了压力诱导配位变化中过渡区域的范围。

General Trends in the Compression of Glasses and Liquids

The present work relates the isothermal volumes of silicate glasses and melts to the combined ionic volumes of their chemical constituents. The relation is an extension of a relation that has already been established for crystalline oxides, silicates, alumosilicates, and other materials that have O2− as a constituent anion. The relation provides constraints on bond coordination, indicates pressure-induced changes in coordination in melts and glasses and interatomic distances, and quantifies the extent of transitory regions in pressure-induced coordination changes.

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
