Preparation method and application of micron-sized Y-Ca co-doped zirconia ceramic microspheres
The invention relates to the field of ceramic materials, and discloses a preparation method and application of micron-sized Y-Ca co-doped zirconia ceramic microspheres. The preparation method comprises the following steps: S1, dissolving a zirconium-containing compound and an yttrium-containing compound in water to obtain a water phase A; dissolving a calcium-containing compound in water to obtain a water phase B; s2, preparing an oil phase; s3, adding the water phase A into the oil phase, and stirring to obtain an emulsion; s4, adding urea and hexamethylenetetramine into the emulsion, and stirring to obtain gel microspheres; s5, washing, centrifuging and drying the gel microspheres, soaking the gel microspheres in the water phase B, and evaporating water under reduced pressure to obtain gel microspheres loaded with a calcium-containing compound; and S6, performing low-temperature presintering and high-temperature sintering to obtain the micron-sized Y-Ca co-doped zirconia ceramic microspheres. The micron-sized Y-Ca co-doped zirconia ceramic microspheres prepared by the preparation method disclosed by the invention are excellent in density, mechanical property and thermal stability, controllable in morphology and uniform in size distribution.
本发明涉及陶瓷材料领域，本发明公开了一种微米级Y‑Ca共掺杂氧化锆陶瓷微球的制备方法、应用。该制备方法包括：S1：将含锆化合物、含钇化合物溶于水中，得水相A；将含钙化合物溶于水中，得水相B；S2：配制油相；S3：将水相A加至油相中，搅拌，得乳液；S4：将尿素和六次甲基四胺加至乳液中，搅拌，得到凝胶微球；S5：凝胶微球经洗涤、离心、干燥，将凝胶微球浸渍于水相B中，减压蒸发水分，得到负载有含钙化合物的凝胶微球；S6：低温预烧、高温烧结，得到微米级Y‑Ca共掺杂氧化锆陶瓷微球。本发明制得的微米级Y‑Ca共掺杂氧化锆陶瓷微球的致密度、力学性能、热稳定性优异且形貌可控、尺寸分布均匀。
