Abstract: This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.

Abstract: A Ca—SiAlON ceramic with enhanced mechanical properties and a method employing micron-sized and submicron precursors to form the Ca—SiAlON ceramic. The Ca—SiAlON ceramic comprises not more than 42 wt % silicon, relative to the total weight of the Ca—SiAlON ceramic. The method employs submicron particles and also allows for substituting a portion of aluminum nitride with aluminum to form the Ca—SiAlON ceramic with enhanced mechanical properties.

Abstract: Methods for producing Polymer Derived Ceramic (PDCs) particles and bulk ceramic components and compositions from partially cured gelatinous polymer ceramic precursors and unique bulk composite PDC ceramics and unique PDC ceramic particles in size and composition. Methods of making fully dense PDCs over approximately 2 μm to approximately 300 mm in diameter for applications such as but not limited to proppants, hybrid ball bearings, catalysts, and the like. Methods can include emulsion processes or spray processes to produce PDCs. The ceramic particles and compositions can be shaped and chemically and materially augmented with enhancement particles in the liquid resin or gelatinous polymeric state before being pyrolyzed into ceramic components. The resulting ceramic components have a very smooth surface and are fully dense, not porous as ceramic components from the sol-gel process.

Abstract: To reduce impurity contents of carbon and oxygen not contributing to light emission, then suppress deterioration of emission intensity of a phosphor, and improve emission efficiency of this phosphor. Therefore, there is provided a firing method of nitride or oxynitride phosphors, wherein a crucible 11 made of nitride is used as a firing container, and firing is performed, with this crucible covered with a lid (container 10), to manufacture the phosphor. The phosphor is expressed by a general composition formula MABOoN3-2/3O:Z in which element M is one or more kinds of elements having bivalent valency, element A is one or more kinds of elements having tervalent valency, element B is one or more kinds of elements having tetravalent valency, O is oxygen, N is nitrogen, and element Z is an activating agent, satisfying o≧0.

Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.
