Zirconia ceramic as well as preparation method and application thereof
The invention belongs to the technical field of biological materials, and particularly relates to zirconia ceramic as well as a preparation method and application thereof. The invention provides zirconium oxide ceramic. The zirconium oxide ceramic is prepared from the following raw materials in parts by mass: 72-78 parts of nano zirconium oxide, 22-28 parts of zirconium oxide fibers, 13-17 parts of a binder, 8-12 parts of a surfactant and 73-78 parts of a lubricant. According to the zirconia ceramic, the zirconium oxide fibers play a role in spacing and crack resistance, and when the zirconium oxide ceramic is subjected to external force, the external force is diffused to the whole zirconia ceramic, so that the bending strength of the zirconia ceramic is enhanced. Meanwhile, the zirconium oxide fibers can also absorb damage energy to inhibit formation and expansion of cracks, so that the effect of toughening the fibers is achieved, and the fracture toughness of the zirconium oxide ceramic is improved.
本发明属于生物材料技术领域，具体涉及一种氧化锆陶瓷及其制备方法和应用。本发明提供了一种氧化锆陶瓷，包括以下质量份数的制备原料：72～78份纳米氧化锆，22～28份氧化锆纤维，13～17份粘结剂，8～12份表面活性剂和73～78份润滑剂。在本发明中，所述氧化锆纤维起间隔阻裂作用，当氧化锆陶瓷受到外力时，外力扩散于整个氧化锆陶瓷，从而增强了氧化锆陶瓷的抗弯强度。同时氧化锆纤维还能够吸收破坏的能量抑制裂纹的形成和扩展，起到纤维增韧的作用，提高了氧化锆陶瓷的断裂韧性。
