摘要

陶瓷材料体内的多孔结构对其性能影响很大

因此研究陶瓷的多孔结构具有重要的意义。但现有的表征技术均不能够观察这种多孔的三维结构。本文采用Nano-CT成像技术对相转化制备的陶瓷中空纤维管壁内的孔结构进行了三维无损观察

得到了壁内孔的形状、走向、孔径分布以及三维结构图

并计算了孔径的大小为0.4–1.5μm

孔隙率为38.31%。从而可以为改善其制造工艺、优化结构参数提供依据

使其更好地在化工、能源、环保等多个领域得到广泛应用。

Abstract

The porous structure of ceramic materials has a great impact on their performance. However

the existing characterization techniques fail to give 3D structure of the ceramics. In this work

nano-CT imaging technique was used to study 3D structure of a ceramic fiber tube prepared by a phase inversion technology. The results showed the shape

direction

size distribution

and 3D map of the pores inside the ceramic wall. The pore size is 0.4–1.5 μm

with a porosity of 38.31%. The data can be used to improve their preparation processes and optimize the structure parameters

for applications in chemical

energy

environmental protection and other fields.
