Properties of Soda Aluminosilicate Glasses
Coordination of Aluminum Ions
An X-ray fluorescence technique has been used to study the coordination number of the aluminum ions in soda aluminosilicate glasses. the fact that the emission wavelength of the Kα line of aluminum is slightly different for aluminum ions in different coordination states is utilized in this technique. Using this small difference in wavelength, it is shown that, depending on the Al/Na ratio, the soda aluminosilicate glasses contain aluminum ions in either fourfold and/or sixfold coordination. the X-ray fluorescence measurements are shown to support the structural model which has been proposed for the soda aluminosilicate glasses to explain the behavior of some of their physical properties.
