The products of reaction between Pb(Zr_<0.53>Ti_<0.47>)O_3(PZT) and PbO-B_2O_3 glasses at 850℃ 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 B_2O_3 content in the glass increased, the amount of dissolved PZT and the thickness of reaction zone increased. When glasses with 40 and 60 mol% B_2O_3 were used, the solid products were Ti-rich PZT and ZrO_2 (ZrO_2-TiO_2 solid solution), which were expected from the phase diagram of the PbO-ZrO_2-TiO_2 system. When a glass with 80 mol% B_2O_3 was used, the solid products were ZrO_2 and TiO_2, 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.
