本文提出了一种新的、简单的、快速的固相法合成Pb（Zr，Ti）O3（PZT）。该方法包括从以所需比例混合的相应氧化物开始，并将装料暴露于微波。通过使一种或多种组成氧化物略微非化学计量，反应速率得到了极大的提高，单相PZT可以在低至600°C的温度下合成。此外，它已被证明，非化学计量的前体和微波辐射的组合使用导致不同的反应途径形成的PZT。此外，微波方法减少了PbO损失。
A novel, simple, and fast solid-state procedure has been demonstrated for the synthesis of Pb(Zr,Ti)O3 (PZT), using microwave radiation. The process consists of starting with the respective oxides mixed in the required proportions and exposing the charge to the microwaves. By making one or more of the constituent oxides slightly nonstoichiometric, enormous enhancement in reaction rates has been achieved, and single-phase PZT can be synthesized at temperatures as low as 600°C. Moreover, it has been shown that the combined use of nonstoichiometric precursors and microwave irradiation leads to different reaction pathways for the formation of PZT. Further, the microwave method diminishes PbO loss.
