Abstract:
Subsolidus equilibria in the PbO-poor part of the TiO 2 –PbO–SiO 2 diagram were studied with the aim of investigating possible applications for low-temperature thick-film dielectrics. The tie lines are between PbTiO 2 and PbSiO 3 , and between PbTiO 3 and SiO 2 . The results show that the TiO 2 , when added to low-temperature softening point glasses, reacts with the PbO from the glass, so forming PbTiO 3 . These results were applied to a low-temperature firing dielectric, consisting of a lead-rich PbO–SiO 2 –B 2 O 3 glass filled with a TiO 2 powder. The conversion of TiO 2 to the PbTiO 3 crystalline phase was observed above firing temperatures of approximately 600 °C. The kinetics of the reaction depend on the particle size of the TiO 2 .
