Abstract: A ceramic article includes a ceramic matrix composite that has a porous reinforcement structure and a ceramic matrix within pores of the porous reinforcement structure. The ceramic matrix composite includes a surface zone comprised of an exterior surface of the ceramic matrix composite and pores that extend from the exterior surface into the ceramic matrix composite. A glaze material seals the surface zone within the pores of the surface zone and on the exterior surface of the surface zone as an exterior glaze layer on the ceramic matrix composite. The glaze material is a glass or glass-ceramic material. The ceramic matrix composite includes an interior zone under the surface zone, and the interior zone is free of any of the glaze material and has a greater porosity than the surface zone.

Abstract: A method for additively manufacturing a ceramic containing article includes selecting a ceramic precursor and a curable resin, determining a ratio of the ceramic precursor to the curable resin required to achieve a desired ceramic microstructure, mixing the ceramic precursor and the curable resin according to the determined ratio, and iteratively building an article by sequentially applying a layer of the mixture and curing the layer using an additive manufacturing machine.
