Silicate glasses with varying SiO2 and Na2O contents were prepared and their viscous flow property at the elevated temperature was studied. When the glass powders were packed and sintered at 550C to examine their feasibility as a low sintering temperature glass frit, contrary to expectations, glasses with lower SiO2 content than 60 mol% showed no vitrification after sintering. High temperature microscopy revealed the viscous flow change of the silicate glasses with varying temperature and duration time and also indicated that the viscous flow was limited at low SiO2 content. X-ray diffraction (XRD) on the sintered samples and Raman spectroscopy were carried out to shed light on the compositional dependency of viscous flow of silicate glasses.
