Abstract: Lead zirconate titanate (PZT) ceramics are typical ferroelectric, piezoelectric and dielectric materials, with high piezoelectric constant and electromechanical coupling coefficient. They are the basic materials for many mechanic and electronic devices, such as ultrasonic transducer, piezoelectric transformer, filter and piezoelectric buzzer. They play an important role in the fields of electronic information, mechanical industry, instruments and meters. This review summarizes the researches on the preparing process of lead zirconate titanate ceramics, including the synthesis of lead zirconate titanate powder, the molding and sintering of the PZT ceramics. The future developments of the lead zirconate titanate ceramics are also discussed at the end.
Key words: lead zirconate titanate; synthesis of PZT powder; rapid prototyping; low temperature sintering
