The products of reaction between Pb(Zr0.53Ti0.47)O3 (PZT) and PbO-B2O3 glasses at 850°C were studied using powder and bulk PZT samples. PZT dissolved in glass phase and solid products were precipitated. The reaction zone composed of glass phase and solid products was formed between bulk PZT and glass. As the B2O3 content in the glass increased, the amount of dissolved PZT and the thickness of reaction zone increased. When glasses with 40 and 60mol% B2O3 were used, the solid products were Ti-rich PZT and ZrO2 (ZrO2-TiO2 solid solution), which were expected from the phase diagram of the PbO-ZrO2-TiO2 system. When a glass with 80mol% B2O3 was used, the solid products were ZrO2 and TiO2, which were supposed to be formed by non-equilibrium reaction sequences. The microstructure of the reaction zone depended on the chemical composition of glass, indicating that the solubility of constituent oxides of PZT was dependent on glass composition.
