摘要： A method of producing a melt infiltrated ceramic matrix composite (CMC) article that includes the steps of: forming a ceramic fiber preform; optionally, rigidizing the ceramic fiber preform with a fiber interphase coating via a Chemical Vapor Infiltration (CVI) process, infiltrating a ceramic slurry into the porous body or preform, conducting one or more secondary operations, and finally, melt infiltrating the preform with molten silicon or a silicon alloy to form the CMC article. The infiltration of a ceramic slurry into a ceramic fiber preform to form a green body is performed along with the use of convection and/or conduction as heat transfer mechanisms, such that the ceramic slurry does not require the incorporation of a pre-gelation material in order for the slurry to remain within the green body during subsequent processing steps.

摘要： Methods of making templated materials using BCP-derived templates, nanocomposites and compositions. The methods use pressure to fill a BCP-derived template with an inorganic material or materials and/or organic material or organic materials to form a templated material. A nanocomposite, which may be a templated material, may include an inorganic material or materials and/N or organic material or materials defining a three-dimensional space and a BCP-derived material disposed on at least a portion of the inorganic material(s) and/or organic material(s). A composition, which may be a templated material where the BCP-derived template is removed, may include an inorganic material or materials and/or organic material or materials defining a three-dimensional space. A device may include nanocomposite(s) and/or composition(s). A device may be an electronic device, energy device, a sensor, or the like.

摘要： A method for enhancing optical properties of sintered, zirconia ceramic bodies and zirconia ceramic dental restorations is provided. The porous or pre-sintered stage of a ceramic body is treated with an yttrium-containing composition and sintered, resulting in sintered ceramic bodies having enhanced optical properties. The enhanced optical properties may be substantially permanent, remaining for the useful life of the sintered ceramic body.
