For low firing temperature, R2O ingredient was added into spray solution containing BaO-ZnO-B2O3-SiO2, used as transparent dielectric layers. The R2O (Li2O, Na2O, K2O) ingredients are important for affording the glass a softening temperature capability at low temperature, as well as for improving melting property of the glass. The glass powders were formed by melting and quenching process in the spray pyrolysis. The BZBS glass powders obtained by spray pyrolysis at preparation temperatures of 1400°C had spherical shapes and dense inner structures. The dielectric layers formed from the BZBS glass powders obtained by spray pyrolysis had clean surface and dense inner structure. The addition of R2O to the glass powders improved the transparencies of the dielectric layers at low firing temperature. The dielectric layer formed from the glass powders with appropriate amount of R2O had transparency of 86% within the visible range even at a low firing temperature of 540oC. |
