Production of porous ceramics, used in environmental and process technology, for separating materials and as catalyst support, involves etching part of non-porous ceramic substrate

摘要

Production of porous ceramics involves etching a part of a non-porous ceramic substrate. Preferred Features: The etching process is a photo-etching process. Silicon carbide is used as the non-porous ceramic substrate. A non-isotropic porous structure is formed by etching.
