摘要

在一系列铝硅酸钠熔体中测定了水在1200℃时的扩散率和溶解度。当Na2O被Al2O3取代时，水在这些熔体中的扩散率和溶解度都降低了。测定了SiO2、Na2O和Al2O3的偏摩尔溶解度。水在这些熔体中的扩散率与熔体的粘度呈反比关系，这可以扩展到包括相同温度下的硅酸钠熔体。这些玻璃的玻璃化温度随水浓度的增加而降低。这种影响的程度与许多其他成分系统相似。

Water diffusion and solubility in sodium aluminosilicate melts

The diffusivity and solubility of water at 1200°C has been measured in a series of sodium aluminosilicate melts. Both the diffusivity and solubility of water in these melts decrease as Na2O is replaced by Al2O3. The partial molar solubilities of SiO2, Na2O and Al2O3 have been determined. The diffusivity of water in these melts exhibits an inverse relationship with the viscosity of the melt, which can be extended to include sodium silicate melts at the same temperature. The glass transformation temperature of these glasses decreases with increasing water concentration. The magnitude of this effect is shown to be similar to that for many other compositional systems.

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.
