Zirconia ceramic and preparation method thereof
The invention discloses zirconia ceramic with high hydrothermal aging resistance and a preparation method thereof. A high-dispersion precursor material can be obtained in a low-temperature flash drying mode, the monoclinic phase rate and the particle size of powder are adjusted in cooperation with a high-speed rapid sanding mode, the zirconia ceramic with the uniform grain size can be obtained, and the grain size is concentrated and distributed between 150 nm and 450 nm. The monoclinic phase rate of the zirconium oxide ceramic prepared by the method is 2.0-5.0% after the zirconium oxide ceramic is soaked in a hydrothermal solution at 140 DEG C for 24 hours, and the monoclinic phase rate of the zirconium oxide ceramic is 5.0-15.0% after the zirconium oxide ceramic is soaked in the hydrothermal solution at 140 DEG C for 72 hours.
本发明公开了一种高抗水热老化性氧化锆陶瓷及其制备方法。通过低温闪蒸干燥方式能够获得高分散的前驱物料，并且配合高速快速砂磨的方式调整粉体的单斜相率和粒度能够获得晶粒尺寸均一的氧化锆陶瓷，晶粒尺寸集中在150nm‑450nm之间分布。本发明制备的氧化锆陶瓷，140℃水热中浸泡24h后的单斜相率在2.0‑5.0％，140℃水热中浸泡72h后的单斜相率在5.0‑15.0％。
