Description

The aim of this work was to study the structural and elastic properties of recycle silica gel glass (denoted as RSGG) using FTIR and ultrasonic technique. The 10CaO – xPbO – (90–x)silica gel glass system (where x = 20, 25, 30, 35, 40 and 45 mol.%) were prepared. In this work, the silica gel was acquired from silica gel degradation in our laboratory. Densities of glass samples with PbO content were measured by Archimedes’s principle using n-hexane as immersion liquid. The longitudinal and shear ultrasonic velocities were measured by using pulse echo technique of 4 MHz at room temperature. Densities data and the ultrasonic velocities data of glass samples were used for calculated the elastic properties such as longitudinal modulus, shear modulus, bulk modulus and Young’s modulus. The results shows that change in elastic properties of the glass samples depend on the concentration of PbO and this can be confirmed using FTIR techniques.
