Environmental barrier coatings for chemical processes and systems

Abstract

A chemical processing unit includes a ceramic-containing structure; and a coating layer in contact with at least a portion of the ceramic-containing structure and capable of reducing or preventing degradation of the ceramic-containing structure by a process fluid at a processing temperature, wherein the process fluid includes two or more of hydrogen gas, oxygen gas, carbon monoxide gas, carbon dioxide gas, water vapor, and a gaseous hydrocarbon; wherein the coating layer includes one or more coating materials following at least one of the chemical formulas: MxOz, MxSiyOz, and MxPyOz, wherein M is a metal, x ranges from 1 to 4, y ranges from 1 to 4, and z ranges from 1 to 7.
