Document Type and Number:
Japanese Patent JP2002537088
Kind Code:
A
Abstract:
The present invention relates to a method for manufacturing a dense and crack-free ceramic membrane which selectively transports oxygen when it is subjected to an oxygen partial pressure gradient, by the following steps: a) preparation of a porous ceramic substrate, with an open network of pores, which allows the transport of gas; b) deposition of a film or coating of an oxygen ion conducting material onto the porous ceramic substrate, by contacting the porous substrate with a colloidal dispersion or slip; c) thermally treating the substrate and film or coating to produce a dense, crack-free membrane on the surface of the porous substrate.
