(57) Abstract: Provided is an article having a silicon-containing substrate and a barrier layer functioning as an environmental / thermal protection barrier coating layer, and a method for producing the same. An article having a silicon-containing substrate and a barrier layer is provided. Here, the barrier layer prevents the formation of a gaseous Si compound when the article is exposed to a condition in which moisture is present at a high temperature. Preferably, said substrate is selected from a silicon-containing ceramic and a silicon-containing metal alloy. |
