Zirconia ceramic bone implantation prosthesis and preparation method thereof
The invention provides a zirconium oxide ceramic bone implantation prosthesis, zirconium oxide ceramic is composed of zirconium oxide, a stabilizer yttrium oxide and a sintering aid, the sintering aid comprises three combination modes of aluminum oxide and scandium trioxide, aluminum oxide and gallium sesquioxide, and scandium trioxide and gallium sesquioxide. The zirconium oxide ceramic bone implantation prosthesis comprises an artificial femoral head and a lining for hip joint replacement and application of the zirconium oxide ceramic bone implantation prosthesis to a knee joint prosthesis for knee joint replacement. According to the preparation method disclosed by the invention, the sintering aids are added into the yttrium oxide-stabilized tetragonal-phase zirconia ceramic, and the sintering aids can generate a synergistic effect while forming a solid solution in zirconia, so that the sintering densification rate of the zirconia ceramic is remarkably improved; high density and fine grain size can be obtained at the temperature as low as 1300 DEG C, and the material has extremely excellent hydrothermal aging phase change resistance.
本发明提供了一种氧化锆陶瓷骨植入假体，氧化锆陶瓷由氧化锆、稳定剂氧化钇和烧结助剂组成，烧结助剂包括氧化铝和三氧化二钪，氧化铝和三氧化二镓，三氧化二钪和三氧化二镓三种组合方式，氧化锆陶瓷骨植入假体包括髋关节置换用人工股骨头和内衬以及膝关节置换用膝关节假体中的应用。本发明中通过向氧化钇稳定的四方相氧化锆陶瓷中添加烧结助剂，烧结助剂在氧化锆中形成固溶体的同时烧结助剂之间会产生协同作用，从而显著提高氧化锆陶瓷的烧结致密化速率，可以在低至1300℃的温度获得高的致密度和细小的晶粒尺寸，具有极其优异的抗水热时效相变能力。
