Abstract
Anelastic spectroscopy (internal friction and the dynamic modulus) was measured by means of a torsion pendulum at 3-12Â Hz, in the range of 100-300Â K, for a KAP metaphosphate glass. Two thermally activated internal friction peaks appeared at â¼190 and â¼250Â K. These peaks were attributed to the behavior of potassium ions (high temperature) and to hydrogen (low temperature). Dynamic modulus showed a gradual decrease with increasing temperature in the range studied for all compositions.
