The thermal and morphological transitions of silica based nanospheres and composites are characterized using a High Temperature Differential Scanning Calorimeter (HTDSC) and Field Emission Scanning Electron Microscope (FESEM). The effects of particle shape and Na ion content on the glass transition and sintering temperatures are investigated by utilizing the temperature controlled furnace of the HTDSC to heat-treat samples to desired temperatures. As sintering temperatures are reduced, silica based glasses or ceramics can be used with a wider variety of substrates and fillers in applications for printable glasses or ceramics, sealants and matrix materials for electronics.
