摘要：

This work describes the temperature evolution of Al-27, Na-23 and F-19 MAS spectra in solid cryolite (Na3AlF6), from room temperature up to 300 degrees C. The description of ionic mobility in the solid is derived from chemical shifts and line-widths evolution for each nucleus with temperature. Exchange two-dimensional experiments on Na-23 directly detect Na mobility and equilibrium constants can be measured.
