Porous ceramic and process thereof

摘要

A process for assembling a porous ceramic coating to a substrate comprising: forming a ceramic matrix tape including a first ceramic powder having a first full density sintering temperature, a second ceramic powder having a second full density sintering temperature and a fugitive filler material (20, 22); placing the ceramic matrix tape on the substrate (24); and heating the ceramic matrix tape and substrate to a sintering temperature above the first full density sintering temperature and below the second full density sintering temperature, wherein the fugitive filler material decomposes during said heating (26).
