| Effect of Cooling Rate on the Structure of Sodium Borate Glasses  | | | | Abstract
| Sodium borate glasses with two different compositions have been prepared using cooling rates in the range 7 • 10" C/s-2 • 10 2 °C/s. Structural characterization has been carried out by X-ray diffraction, and glass transition temperatures have been measured by Differential Scanning Calorimetry. The samples exhibit slightly different density values and glass transition temperatures. However, radial distribution functions appear extremely similar and the sodium coordination shell does not change in going from fast to slowly quenched glasses, showing that the short and medium range order is not affected by thermal treatment. | | | |
