Abstract In this work a phase inversion method is effectively applied towards the formation of technical ceramics such as mm sized yttria stabilized zirconia beads. For the first time yttria stabilized zirconia spherical beads of uniform mm size diameter and hierarchical porosity are prepared by a simple one pot method utilizing phase inversion and templating synthesis. Solvent exchange and subsequent thermal treatment developed an open porous network of radial hierarchical porosity. Multimodal pore size distribution ranging within 3 orders of magnitude was identified and porosity values up to 74% were measured.

一种制备具有分级孔隙率的陶瓷珠的简便方法

摘要 在这项工作中，一种相转化方法有效地应用于技术陶瓷的形成，例如毫米尺寸的氧化钇稳定氧化锆珠。首次通过简单的一锅法利用相转化和模板合成制备了均匀 mm 尺寸和分级孔隙率的氧化钇稳定氧化锆球珠。溶剂交换和随后的热处理形成了径向分级孔隙率的开放多孔网络。确定了 3 个数量级范围内的多峰孔径分布，并测量了高达 74% 的孔隙率值。
