Jung, S.K. Hong, J.S. Cho, Y.C. Kang] Fine-sized BaO-ZnO-B2O3-SiO2 (BZBS) glass powders were directly prepared by high temperature spray pyrolysis. The hollow glass powders prepared at low preparation temperature of 1000°C had a low density of 2.65g/cm3. However, the densities of the BZBS powders obtained at preparation temperatures of 1200 and 1400°C were each 3.92 and 4.13g/cm3. The mean size of the BZBS glass powders prepared by spray pyrolysis at preparation temperature of 1400°C was 0.98μm. The glass transition temperature (Tg) of the prepared BZBS glass powders was 518.9°C. The dielectric layers formed from the prepared BZBS glass powders with a dense structure had a clean surface and a dense inner structure without voids at the firing temperature of 580°C. The transparencies of the dielectric layers formed from the prepared BZBS glass powders were higher than 90% within the visible range. Springer-Verlag, 2007 Jung D.S.
