Abstract

Density and molar volume of MgO–Al2O3–SiO2, MgO–CaO–SiO2 and MgO–CaO–Al2O3–SiO2 glasses have been correlated with the structure by following the change in type and concentration of structural units with composition. It is assumed that for (MgO+CaO)≥Al2O3 all Al atoms form AlO4 tetrahedra. The type of modified units of SiO2 (Q3 and Q2) are determined by the ratio [(MgO+CaO)−Al2O3]/SiO2. In the case of (MgO+CaO)

MgO-Al2O3-SiO2、MgO-CaO-SiO2和MgO-CaO-Al2O3-SiO2玻璃的密度和摩尔体积随结构单元类型和浓度的变化而变化。假设(MgO+CaO)≥Al2O3时，所有Al原子形成AlO4四面体。SiO2 (Q3和Q2)改性单元的类型由[(MgO+CaO)−Al2O3]/SiO2的比值决定。在(MgO+CaO)

期刊介绍： Physics and Chemistry of Glasses accepts papers of a more purely scientific interest concerned with glasses and their structure or properties. Thus the subject of a paper will normally determine the journal in which it will be published.
