Structural and Thermal Properties of Quaternary B2O3 ? Na2O ? RO?MnO2 (R=Mg, Zn, Cd) Glasses
Abstract
The quaternary glass systems of B2O3 ? Na2O ? RO ? MnO2 (R=Mg, Zn, Cd) with different compositions of MnO2 are prepared by melt-quenching technique. Amorphous nature of these glasses has been confirmed from their XRD profiles. Density of all the glass samples is measured using relative measurement method. FTIR spectra of these glasses are recorded over a continuous spectral range (4000 ? 400 cm-1) as an attempt to study their structural units. Thermal properties of the glasses are studied using differential thermal analysis. The longitudinal and shear ultrasonic velocities are measured for all the compositions at 303K and at 10MHz frequency using the Pulse Echo Overlap method. Elastic moduli and other parameters such as molar volume, Poisson?s ratio, acoustic impedance, microhardness and Debye temperature are calculated from density and velocity data, and they are used to gain knowledge about the structural and mechanical properties of these glasses, and are correlated with the rigidity and compactness of the glass systems
