COMPONENT IN A COMBUSTION SYSTEM, AND PROCESS FOR PREVENTING SLAG, ASH, AND CHAR BUILDUP

摘要

Disclosed herein is a component in a combustion system comprising a composite, the composite comprising silicon carbide; and a refractory metal silicide comprising a phase selected from Rm₅Si₃, Rm₅Si₃C, RmSi₂, and a combination thereof; wherein Rm is a refractory metal selected from molybdenum, tungsten, and a combination thereof. Also disclosed is a process for preventing slag, ash, and char buildup on a surface, comprising disposing a first surface of the composite on the surface; replacing a component comprising the surface with a component consisting of the composite; or a combination thereof.
