Abstract

The spherical shape Pb-based glass powders with the mean sizes between 370 and 990 nm were prepared by spray pyrolysis. The transparencies of the dielectric layers were slightly affected by the mean sizes of the Pb-based glass powders at the firing temperature of 580 °C. However, the transparencies of the dielectric layers fired at low temperatures between 460 and 520 °C were strongly affected by the mean sizes of the Pb-based glass powders. The transparencies of the dielectric layers formed from the glass powders with the mean size of 370 nm changed from 96.1 to 68.2% when the firing temperatures of the dielectric layers were changed from 580 to 440 °C. On the other hand, the transparencies of the dielectric layers formed from the glass powders with the mean size of 990 nm changed from 95.2 to 16.4% at the same firing temperatures ranges. The Pb-based glass powders with fine size melted at low firing temperatures. Therefore, dielectric layers formed from the Pb-based glass powders with fine size had dense inner structure and high transparencies even at low firing temperatures.
