    Abstract: Disclosed is a method for providing a crystalline ceramic material. In an example, the method includes providing a silicon-containing preceramic polymer material that can be thermally converted to one or more crystalline polymorphs. The silicon-containing preceramic polymer material includes dispersed therein an effective amount of dopant particles. The silicon-containing preceramic polymer material is then thermally converted to the silicon-containing ceramic material. The effective amount of dopant particles enhance the formation of at least one of the one or more crystalline polymorphs, relative to the silicon-containing preceramic polymer without the dopant particles, with respect to at least one of formation of a selected polymorph of the one or more crystalline polymorphs formed, an amount formed of a selected polymorph of the one or more crystalline polymorphs formed, and a temperature of formation of the one or more crystalline polymorphs.

    Abstract: A method of fabricating a ceramic article includes serially depositing first, second and third different materials within a porous structure using, respectively, first, second and third different processing techniques, to form a ceramic-containing article. The first, second and third materials differ by at least one of composition and microstructure. The first, second and third different processing techniques differ by at least one of modes of delivery of precursor materials into the porous structure and formation mechanisms of the first, second and third different materials from the precursor materials. The deposition of the first material is controlled such that there are first residual voids in the porous structure in which the second material is deposited. The deposition of a second material is controlled such that there are second residual voids in the porous structure in which the third material is deposited.
