Abstract
This paper describes a new process based on electrostatic dry deposition (EDD), which provides a novel and simple option for the fabrication of porous ceramic filter. Fine Al2O3 particles (average particle size less than 5μm) suspended in gas phase were deposited on porous ceramic substrate in the form of particle chains under the action of an electrostatic field without corona generation. After sintering, a three-dimensional network layer was obtained. This process will be simpler than 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 to form porous layer on material surface.
