Viscoelastic Relaxation in Hydrated Melts

Abstract
Measurements of longitudinal absorption for the system Ca(NO3)2·3.2H2O reveal the presence of a relaxation process. This relaxation is viscoelastic, i.e., the liquid is transformed into a pseudoglass. Shear velocity measurements conform the appearance of a viscoelastic relaxation with the condition τv≈τs in this system.
