Abstract
We examined the influence of barium oxide addition on the structure and properties of SiO2-Al2O3-Na2O-K2O-MgO glass-ceramics. Glass-ceramics were prepared with constant SiO2/Al2O3 and Na2O/K2O ratios of 6.5 and 1.04, respectively, and the MgO content was maintained at 10.56 wt%. The barium oxide content was set at 4 wt%, 9 wt%, and 14 wt%. The weight ratios were recalculated from the BaCO3 added. To determine the microstructure of the glassy materials, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), medium (MIR) and far infrared analysis (FIR), and Raman spectroscopy were used. Significant differences were observed in the phase composition and in the silica-alumina-oxide network of the glassy phase, which could be related to changes in the amount of barium oxide. The characteristic temperatures (beginning of sintering, sphere, half-sphere and melting), which were measured by using hot stage microscopy and dilatometry, also showed changes.
