The products of reaction between Pb (Zr_<0.53>Ti_<0.47>)O_3(PZT) and glasses in the PbO-SiO_2 and PbO-B_2O_3-SiO_2 systems at 850℃ were studied using powder and bulk PZT samples. A reaction zone was formed between bulk PZT and the glass. The microstructure of the reaction zone changed with the amount of PZT dissolved in the glass phase, which was dependent on the activity of PbO in both the glass phase and PZT. When the amount of dissolved PZT was small, as in the reaction between PZT and 60 mol% PbO・40 mol% SiO_2 glass, the glass phase penetrated into grain boundaries of PZT, and no solid reaction product was formed. When the amount of dissolved PZT was intermediate, as in that between PZT and 40 mol% PbO・60 mol% SiO_2 glass, the glass phase penetrated into the PZT pellet and ZrO_2 particles were precipitated in the glass phase. When the amount of dissolved PZT was large, as in those between PZT and 60 mol% PbO・20 mol% B_2O_3・20 mol% SiO_2 glass and 40 mol% PbO・30 mol% B_2O_3・30 mol% SiO_2 glass, the reaction zone was formed, which was composed of Ti-rich PZT and ZrO_2 particles dispersed in the glass phase.
