Zirconia ceramics containing glass phase
The invention relates to zirconia ceramic containing a glass phase, the zirconia ceramic is composed of 1.0-5.5 wt% of a YASZ glass phase and the balance of a 3Y-TZP crystal phase, the YASZ glass phase is located between crystal grains of the 3Y-TZP crystal phase, the YASZ glass phase is composed of 15-35 wt% of Y2O3, 10-30 wt% of Al2O3, 35-55 wt% of SiO2 and 4-10 wt% of ZrO2, and the dihedral angle formed between the YASZ glass phase and the 3Y-TZP crystal phase is 62-85 degrees. The invention also relates to a bone implant prosthesis prepared from zirconia ceramics containing a glass phase.
本发明涉及含有玻璃相的氧化锆陶瓷，由1.0‑5.5wt％的YASZ玻璃相和余量的3Y‑TZP晶体相组成，所述YASZ玻璃相位于所述3Y‑TZP晶体相的晶粒之间，其中，所述YASZ玻璃相由15～35wt％Y2O3、10‑30wt％Al2O3、35～55wt％SiO2和4‑10wt％ZrO2组成，并且所述YASZ玻璃相和所述3Y‑TZP晶体相之间形成的二面角为62～85°。本发明还涉及由含有玻璃相的氧化锆陶瓷制备的骨植入假体。
