我们报告了一种用于制备高质量陶瓷的新型振荡压力辅助热压工艺。与传统无压烧结（PS）和热压（HP）制备的样品相比，振荡压力辅助热压（OPAHP）制备的氧化锆陶瓷具有更高的密度、更小的晶粒尺寸和更均匀的结构。更引人注目的是，OPAHP样品的强度达到1556 MPa，远高于其他两种技术制备的样品。结果表明，OPAHP 是一种更有效的制备高质量氧化锆的技术，这可能适用于其他材料系统。
We report a novel oscillatory pressure-assisted hot-pressing process for preparing high-quality ceramics. Compared with the samples prepared by conventional pressureless sintering (PS) and hot-pressing (HP), the zirconia ceramic prepared by oscillatory pressure-assisted hot-pressing (OPAHP) exhibited a higher density, smaller grain size, and more homogeneous structure. More remarkably, the strength of the OPAHP sample reached 1556 MPa, which is much higher than the samples prepared by other two techniques. The results suggest that OPAHP is a more effective technique for preparing high-quality zirconia, which is likely applicable to other material systems.
