Theoretical analysis of ultrasonic wave absorption and
elastic moduli for TeO2-V2O5-Sm2O3 glass system is presented. A correlation
between low temperature ultrasonic relaxation parameters and other physical
(elastic) properties for this glass system was achieved according to a model
presented by Bridge and Patel. Correlation coefficients greater than 96% were
obtained indicating that correlations between ultrasonic attenuation and
activation energy at low temperatures and the bulk modulus of this glass system
at room - temperature (through the two crucial structural parameters, number of
anions and anion-cation force) exist.
