Black zirconia ceramic and preparation method thereof
The invention belongs to the technical field of ceramics, and discloses a black zirconia ceramic and a preparation method thereof. The preparation method of the black zirconium oxide ceramic comprises the following steps: mixing zirconium oxide, yttrium oxide, aluminum oxide, titanium oxide, nickel oxide, iron oxide, a dispersing agent and water, and carrying out ball milling to obtain mixed slurry; and drying the mixed slurry to obtain zirconia ceramic powder, pressing to obtain a ceramic blank, and roasting to obtain the black zirconia ceramic. According to the invention, the oxide raw material is directly refined to be less than 200nm by adopting a ball milling technology, only a proper amount of deionized water and a dispersing agent are needed in the preparation process, the introduction of acid radical ions is avoided, the energy consumption is low, the production efficiency is high, the method is safe and pollution-free, and the development requirements of new material preparation in the future are met; in addition, the zirconia ceramic provided by the invention has excellent mechanical properties and optical properties.
本发明属于陶瓷技术领域，公开了一种黑色氧化锆陶瓷及其制备方法。该黑色氧化锆陶瓷的制备方法，包括以下步骤：将氧化锆、氧化钇、氧化铝、氧化钛、氧化镍、氧化铁、分散剂和水混合，进行球磨，得到混合浆料；将混合浆料进行干燥处理，得到氧化锆陶瓷粉体，然后进行压制，得到陶瓷胚体，经焙烧得到黑色氧化锆陶瓷。本发明采用球磨技术将氧化物原料直接细化至200nm以下，制备过程只需要适量去离子水及分散剂，避免了酸根离子的引入，能源消耗低，生产效率高，安全无污染，符合未来新材料制备的发展要求；此外，本发明提供的氧化锆陶瓷具有优良的机械性能和光学性能。
