Abstract Transient liquid phase processing was investigated to decrease processing temperatures while maintaining useful piezoelectric properties in the lead zirconate titanate (PZT) system. Niobium oxide(Nb_2O_5) modified crystalline PZT (PZTN) powder was combined with lead silicate (PS; PbO-SiO_2) glass powder and crystalline titania, zirconia, and niobia. Firing above the melting temperature of the lead silicate (PS; Tm ≒ 714^{°k}C) resulted in liquid phase densification of the PZTN followed by dissolution of the titania, zirconia, and niobia into the liquid phase, and crystallization of additional PZTN. The addition of crystalline titania, zirconia, and niobia to react with the lead oxide from the lead silicate phase resulted in an increase in the dielectric and Piezoelectric properties.
