The application of microwave synthesis – sintering to the fabrication of zirconolite (CaZrTi₂O₇), as a candidate waste form for plutonium immobilization, was demonstrated as an alternative to conventional solid state reactive sintering. Ceramics of near-theoretical density were produced with a rapid dwell time of just 10 min at 1400 °C, and overall throughput time of just 60 min. In comparison with processing at 1200 °C, elevation of the processing temperature to 1400 °C significantly improved the microstructure homogeneity and reduced the porosity. The ability to sinter in air presents the potential advantage and allows for flexible control of redox conditions.

微波合成烧结在锆石（CaZrTi ₂ O ₇）的制造中的应用已作为常规固相反应烧结的替代方法，作为z固定化的候选废料，已得到证明。接近理论密度的陶瓷在1400°C的快速停留时间仅为10分钟，总吞吐时间仅为60分钟。与在1200°C下进行处理相比，将处理温度提高到1400°C可以显着改善微观结构的均匀性并降低孔隙率。在空气中烧结的能力展现了潜在的优势，并允许灵活控制氧化还原条件。
