Zirconium oxide microspheres and preparation method thereof
The invention provides a zirconia microsphere and a preparation method thereof, and the preparation method comprises the following steps: mixing and stirring N, N '-methylene bisacrylamide, acrylamide, a dispersant and water to obtain slurry A; mixing 2.5 Y-ZrO2 calcined powder and the slurry A, performing ball milling, adding a defoaming agent and an initiator, and uniformly mixing to obtain slurry B; taking the slurry B as a dispersion phase and liquid paraffin as a mobile phase, carrying out mobile phase shearing to obtain a microsphere precursor, and adding a catalyst solution into the middle end of a microchannel to obtain a cured zirconium oxide microsphere biscuit; and cleaning and drying the zirconium oxide microsphere biscuit, and carrying out low-temperature presintering and high-temperature sintering to obtain the zirconium oxide microsphere. According to the method, low-temperature pre-sintering and high-temperature sintering are combined, so that the density of the zirconium oxide microspheres is improved, the low-abrasion zirconium oxide microspheres are obtained, and the method has great application space in the fields of grinding dispersion of high-added-value ceramics with very high product purity requirements, biochemistry, medical industry and the like.
本发明提供一种氧化锆微球及其制备方法，其包括将N,N'‑亚甲基双丙烯酰胺、丙烯酰胺、分散剂、水混合搅拌后，得到浆料A；将2.5Y‑ZrO2煅烧粉和浆料A混合后球磨，再加入消泡剂和引发剂，混匀后得到浆料B；以浆料B作分散相，液体石蜡作流动相，进行流动相剪切得到微球前驱体，在微通道的中端加入催化剂溶液，得到固化的氧化锆微球素坯；将氧化锆微球素坯清洗、烘干，进行低温预烧结和高温烧结，得到氧化锆微球。本发明低温预烧结和高温烧结相结合，提高了氧化锆微球的密度，获得了低磨耗的氧化锆微球，在产品纯度要求很高的高附加值陶瓷的研磨分散、生物化学、医药工业等领域的应用空间极大。
