Abstract
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; placing the ceramic matrix tape on the substrate; 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.
