Cerium oxide/yttrium oxide composite stabilized zirconium oxide grinding medium and preparation method thereof
The invention provides a cerium oxide/yttrium oxide composite stabilized zirconium oxide grinding medium and a preparation method thereof, and the method comprises the following steps: 1, mixing zirconium oxide, cerium oxide, yttrium oxide and kaolin, adding a proper amount of a dispersant and water, and grinding to obtain slurry; 2, carrying out centrifugal spray drying on the slurry to obtain cerium oxide/yttrium oxide composite stable zirconium oxide powder; step 3, adding a binder into the cerium oxide/yttrium oxide composite stabilized zirconia powder, and carrying out rolling forming to prepare a spherical grinding medium green body; and 4, sintering and polishing the spherical grinding medium green body to obtain the cerium oxide/yttrium oxide composite stable zirconium oxide grinding medium. According to the method, low particle size and high specific surface are obtained through high-temperature ball milling, and the stabilizer is promoted to be dissolved in zirconium oxide crystal lattices through heat treatment, so that the sintering activity is improved, the sintering temperature is reduced, and the production cost is reduced.
本发明提供一种氧化铈/氧化钇复合稳定氧化锆研磨介质及制备方法，该方法包括：步骤一、将氧化锆、氧化铈、氧化钇和高岭土混合，再加入适量分散剂和水研磨得到浆料；步骤二、浆料进行离心喷雾干燥得到氧化铈/氧化钇复合稳定氧化锆粉；步骤三、再将氧化铈/氧化钇复合稳定氧化锆粉加入粘结剂，滚动成型制得球形研磨介质生坯；步骤四、球形研磨介质生坯烧结、抛光后得到氧化铈/氧化钇复合稳定氧化锆研磨介质。该方法通过高温球磨获得低粒径、高比表的同时也通过热处理促进稳定剂固溶到氧化锆晶格中，从而提高烧结活性、降低烧结温度，降低生产成本。
