Abstract
The clustering and precipitation of Mg-vacancy pairs in LiF (TLD-100) has been studied by means of dielectric loss measurements as a function of aging time at different temperatures. Rapid quenching techniques ensured that no (Mg2+V-) clustering had taken place prior to aging as in many previous studies. Clustering was found to follow third-order kinetics and a trimer binding energy of 0.89 eV was determined. The precipitation kinetics are represented in a time-temperature-transformation (TTT) plot.
