Description
Preparation of the glass 6 samples in the system 10SrO – $x$PbO – $(90-x)$Silica gel where $x$ = 20, 25, 30, 35, 40 and 45 mol%. The principle of Archimedes was used to measure the density of the glass samples. The ultrasonic velocities of the glasses were determined at room temperature by using pulse echo technique. The velocity data of the glass system have been used to find the elastic moduli. FTIR spectroscopy which measure in range 400-2000 cm${}^{-1}$ were used to study the structural properties of the glass samples. The results supported our discussion of the formation of NBO and BO in the structural of glass systems.
