Physical and chemical properties of beads glasses

Abstract

Abstract The chemical and physical characterization of glass beads in different sizes with diameters 3 mm, 4 mm, 5 mm and 6 mm, respectively, have been studied in this paper. The X-ray Diffraction (XRD) analysis exhibited that the structure of glass bead is amorphous, and the diffraction peaks for annealing sample 400 °C and 600 °C, respectively, are seen at 2θ values ranged (26.165°–29.47°). The Scanning Electron Microscopy (SEM) and chemical composition measurement by Energy Dispersive Spectrometer (EDS) system have been conducted; they exhibited that all the samples have the same smooth surface, and the chemical composition analysis showed that the weight percentage of oxygen and silicon were dominant elements in the main structure of glass beads as well as some other elements like Ca, Mg, and Na were observed.
