Coated ceramic structure and method of making same

摘要

A ceramic structure comprises a reticulated ceramic portion defined by a plurality of interconnecting webs having a pore distribution of between 5 and 125 (ppi) pores per linear inch and a ceramic coating portion sintered to the webs along a surface defined by one face of said coating. The coating has a thickness less than about 3 millimeters. The ratio of average thickness of the coating to the thickness of the web forming the reticulated ceramic is between 1 and 10.
