Abstract: A composite ceramic composition including a boron carbide phase and a method of forming the same. The composite ceramic composition includes a tungsten boride phase, a transition metal boride phase. The composite ceramic composition may also include a carbon disposed in solid solution with at least the tungsten boride phase and the transition metal boride phase. The transition metal boride phase may include a boride of at least one metal chosen from Cr, Nb, and Zr.

Abstract: A method for forming a sintered composition including providing a slurry precursor including a lithium-, sodium-, or magnesium-based compound; tape casting the slurry precursor to form a green tape; and sintering the green tape at a temperature in a range of 500° C. to 1350° C. for a time in a range of less than 60 min to form a sintered composition, such that the slurry precursor further includes a solvent and dispersant. The dispersant may include an amine compound, a carboxylic acid compound, or combinations, mixtures, or salts thereof.

Abstract: The disclosure relates to methods of fabricating of ceramic structures, and more particularly to methods of fabricating ceramic structures having profiled surfaces and more particularly to methods of fabrication of ceramic mirror blanks. In one embodiment, a method of forming a shaped ceramic article, includes: forming, via one of a cold-pressing process or pressure casting process, a green ceramic article comprising a first surface, an opposing second surface and at least one high aspect ratio feature shaped into at least one surface; heating the green featured ceramic part to form a debound featured ceramic part; and densifying the debound featured ceramic part via one of a pressureless sintering process or a hot-pressing process.
