Abstract
Brillouin scattering (GHz) experiments were performed on a viscous 60 % KNO3 - 40 % Ca((NO3)2 mixture (mol. %) in a temperature range of 90-3800 C. Sound velocities for both the transverse and longitudinal waves were measured as well as the absorption. A single relaxation time behaviour was revealed for temperatures > 2000°C. The temperature dependence of the relaxation time was determined in a wide range, >3000°, above the glass transition.
