The invention discloses zirconia ceramic. The zirconia ceramic comprises the following components in percentage by mol: 90 to 92 mol% of zirconia, 5 to 6.5 mol% of cerium oxide and 2 to 4 mol% of yttrium oxide. The invention further discloses a preparation method of a ceramic scalpel. The preparation method comprises the following steps: carrying out ball milling on mixed particles of zirconia, cerium oxide and yttrium oxide, subjecting the ball-milled mixed particles to mixing and stirring with an adhesive, and successively carrying out defoaming, casting, laminating, isostatic pressing, degreasing and sintering. According to the zirconia ceramic and the ceramic scalpel, zirconia is used as a basic material, and rare earth oxides, namely yttrium oxide and cerium oxide are added, so a formed zirconia-based material can obtain higher toughness and hardness and has excellent mechanical properties; and through interaction of multiple stabilizers, the properties of the material in other aspects such as aging resistance and phase stability are optimized.
本申请公开一种氧化锆陶瓷，包括氧化锆、氧化铈和氧化钇，其中氧化锆的物质的量百分比为90～92mol.％，氧化铈的物质的量百分比为5～6.5mol.％，氧化钇的物质的量百分比为2～4mol.％。本申请还公开一种陶瓷手术刀的制备方法，通过氧化锆、氧化铈和氧化钇的混合颗粒进行球磨、与粘合剂混合搅拌、除泡、流延、叠片、等静压、脱脂和烧结的处理。本发明的氧化锆陶瓷、陶瓷手术刀，以氧化锆为基础材料，添加稀土氧化物氧化钇和氧化铈，使氧化锆基材料能获得更高的韧性和硬度，具有优良的机械力学性能，也通过多元稳定剂的相互作用，优化材料在如抗老化与相稳定性等其他方面的性能。
