Composites made from BaTiO3 with a high addition of B2O3–Bi2O3–SiO2–ZnO (BBSZ) glass (50–90wt.%) were sintered at 450°C and 400°C. The shrinkage rates of the compositions as a function of temperature were determined by dilatometer. XRD patterns, Raman spectra and microstructures revealed that an additional phase of Bi24Si2O40 was formed when samples were sintered at 450°C and the glass content exceeded...
