Zirconia ceramics with porous structure have been prepared by solid-state reaction using yttria-stabilized zirconia and stearic acid powders. Analysis of its microstructure and phase composition revealed that a pure zirconia phase can be obtained. Our results indicated that its porosity and pore size as well as the mechanical characteristics can be tuned by changing the content of stearic acid powder. The optimal porosity and pore size of zirconia ceramic samples can be effective for the increase of surface roughness, which results in higher cell proliferation values without destroying the mechanical properties.
采用氧化钇稳定的氧化锆粉末和硬脂酸粉末，通过固态反应制备了具有多孔结构的氧化锆陶瓷。对其微观结构和相组成的分析表明，可以获得纯氧化锆相。我们的结果表明，通过改变硬脂酸粉末的含量，可以调节其孔隙率、孔径以及力学特性。氧化锆陶瓷样品的最佳孔隙率和孔径可有效增加表面粗糙度，从而在不破坏力学性能的情况下获得更高的细胞增殖值。
