Abstract
A new method for fabricating porous ceramics and functional fibers was devised. In this work, fine dielectric particles, Al2O3, and conductive particles, LSM (Sr-doped LaMnO3), suspended in gas phase were controlled to form chain aggregates under the action of an electrostatic field. After sintering, the chain aggregates became fiber-like, and a three-dimensional network layer of Al2O3 was obtained. The separation experiment of silica particles from water showed that it had good performance. This process will be simpler than the chemical vapor deposition (CVD) method because fine particles are from powder dispersion, not prepared by CVD. Furthermore, many kinds of commercial powder products can be used directly.
