Abstract

Bismuth-based glass powders with different quantities of Li2O were directly prepared by high-temperature spray pyrolysis. The bismuth-based glass powders were completely spherical and submicron in size irrespective of the quantities of the Li2O additive. The high optical transmittances of the dielectric layers formed from the glass powders obtained by spray pyrolysis were due to the decrease in the glass-transition temperatures of the glass powders with the addition of Li2O. The 'yellowing phenomenon' was not observed in the dielectric layers formed from the glass powders obtained by spray pyrolysis, whereas it occurred in the dielectric layers formed from the glass powders obtained through the conventional melting process.
