【摘要】 采用液相前驱体浸渗法掺杂技术,在Zr O₂坯体引入有色离子,通过扩散溶入基体,制备了颜色纯正、掺杂均匀的黑、蓝、粉、绿色氧化锆陶瓷。XRD分析表明,样品的主晶相为氧化锆四方相。采用CIE L*a*b*系统研究了样品的色度,确定4种颜色样品具有相应的色度。SEM分析表明晶粒粒度均匀,无明显缺陷。力学性能表明几种彩色陶瓷具有较高的强度和韧性。更多还原

【Abstract】 A series of blue, pink, green and black zirconia ceramics with pure color and uniform doping were prepared by the method of liquid phase precursor impregnation. XRD analysis indicates that the main crystal phase of the sample is zirconia tetragonal phase. The CIE L*a*b* system was used to study the chromaticity of the samples, and the four color samples were determined to have corresponding chromaticity. SEM analysis shows that the grain size is uniform and no obvious defects are observed. Mechanical properties analysis reveals that the colored ceramics have high strength and toughness.更多还原
