Viscoelastic and ultrasonic relaxation in molten mixture of acetamide and calcium nitrate
Abstract
Ultrasonic and viscoelastic relaxation spectra were determined for a mixture of acetamide and calcium nitrate [X (acetamide)= 0.7644]. Retardation phenomena are present in the viscoelastic relaxation spectrum and they seem to be affected by the type of container used; the ultrasonic spectrum is due to a chemical equilibrium. There was no evident structural phenomenon.
