Glasses of the general formula (50- x )P 2 O 5 - 30ZnO - 20Li 2 O - ( x )SrCO 3 , where (0.00 ≤ x ≤ 5.00 mol%) were prepared via the melt-quench technique. The mechanical properties of the glass are utilized by using ultrasonic testing. The absence of distinct and Bragg peaks in XRD spectra, confirming the amorphous nature of samples. The glass densities are found increases as well as the packing densities with respect to SrCO 3 concentration, which leading to the decrease in molar volume values, indicating the rigidity of the glasses. The ultrasonic results and other measured parameters attribute to the Sr ion increase in the cross-link density by the formation of P-O-Sr due to the value of Poisson’s ratio obtained are between range of 0.1 to 0.2.
