Abstract

The microwave sintered zirconia ceramics with 0, 1, 3, and 5 wt% TiO2 addition at a low sintering temperature of 1300°C and a short holding time of 1 hour were investigated. Effect of contents of TiO2 addition on microstructure and mechanical properties of microwave sintered zirconia bioceramics was reported. In the sintered samples, the main phase is monoclinic zirconia (m-ZrO2) phase and minor phase is tetragonal zirconia (t-ZrO2) phase. The grain sizes increased with increasing the TiO2 contents under the sintering temperature of 1300°C. Although the TiO2 phase was not detected in the XRD pattern, Ti and O elements were detected in the EDS analysis. The presence of TiO2 effectively improved grain growth of the ZrO2 ceramics. The Vickers hardness was in the range of 125 to 300 Hv and increased with the increase of TiO2 contents. Sintering temperature dependence on the Vickers hardness was also investigated from 1150°C to 1300°C, showing the increase of Vickers hardness with the increase of the sintering temperature as well as TiO2 addition.

摘要

研究了在1300°C的低烧结温度和1小时的短保温时间下添加0、1、3和5 wt% TiO₂的微波烧结氧化锆陶瓷。报道了TiO₂添加量对微波烧结氧化锆生物陶瓷微观结构和力学性能的影响。在烧结样品中，主相为单斜氧化锆（m-ZrO₂）相，次相为四方氧化锆（t-ZrO₂）相。在1300°C的烧结温度下，晶粒尺寸随TiO₂含量的增加而增大。虽然在XRD图谱中未检测到TiO₂相，但在EDS分析中检测到了Ti和O元素。TiO₂的存在有效地促进了ZrO₂陶瓷的晶粒生长。维氏硬度在125至300 Hv范围内，并随TiO₂含量的增加而增大。还研究了1150°C至1300°C范围内烧结温度对维氏硬度的影响，结果表明维氏硬度随烧结温度以及TiO₂添加量的增加而增大。
