PURPOSE: Provided are an article having a silicon-containing substrate and a barrier layer functioning as an environmental/thermal protective barrier coating layer. CONSTITUTION: An article having a silicon-containing substrate and a calcium- containing barrier layer is provided. Herein, the barrier layer prevents the formation of a gaseous Si-compound When the article is exposed to a high temperature moisture present condition. Preferably, the substrate is selected from silicon-containing ceramic and a silicon-containing metal alloy.
