Methods of making environmental barrier coatings for high temperature ceramic components using sintering aids
Methods for making an environmental barrier coating (12) using a sintering aid comprising combining at least water, and a primary transition material comprising mullite, BSAS, or a mullite/BSAS mixture to produce a transition layer slurry; applying the transition layer slurry to a ceramic component (10); combining at least water, and a primary outer material comprising BSAS to produce an outer layer slurry; applying the outer layer slurry to the component having the applied transition layer slurry; and sintering the component to produce the environmental barrier coating having at least a transition layer (16) and an outer layer (18) wherein after applying at least one of the transition layer slurry or the outer layer slurry, the component is dried and the at least one layer is infiltrated with a sol-gel solution, and wherein the transition layer comprises a porosity of from 0% to about 30% by volume of the transition layer, and the outer layer comprises a porosity of from 0% to about 15% by volume of the outer layer.
