摘要：
Borate glasses are of interest for many electronic applications like electronic packages and in vacuum systems as sealing glass. The aim of this work is to study the effect of Pb2O3 2 O 3 and SiO2 2 additives on the structural and characteristics of borate glass. Binary borate glass of BaO.B2O3 2 O 3 was synthesized by melt-quenching technique. The additives were introduced to the glass by substitution with BaO and B2O3. 2 O 3 . Two Batches of six recipes were prepared. All the synthesized glasses were transparent. The glass transition temperature (Tg) g ) has varied according to the chemical composition. Recipe G3 exhibits the lowest Tg g around 440 degrees C, while G2 and G4 show high thermal stability. Coexisting of Pb2+ 2+ and Si4+ 4+ led to high dielectric constant for glass G5 and G6.
