    摘要： A ceramic composite for light conversion, which can make the fluorescence dominant wavelength longer up to 580 nm, further arbitrarily adjust the wavelength in the range of 570 to 580 nm, and undergoes no decrease in fluorescence intensity even when the fluorescence dominant wavelength is made longer, with luminescence unevenness suppressed. A light-emitting device comprising ceramic composite mentioned above. The ceramic composite for light conversion is a solidified body including a composition expressed by the following formula (1), where the composition has a structure where at least two oxide phases of a first phase and a second phase are continuously and three-dimensionally entangled mutually, and the ceramic composite for light conversion is characterized in that the first phase is a (Tb, Y)3Al5O12 phase activated with Ce for producing fluorescence, whereas the second phase is an Al2O3 phase.

    摘要： This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal (e.g., a parent metal vapor) is induced to react with at least one solid oxidant-containing material to result in the directed growth of a reaction product which is formed from a reaction between the parent metal and the solid oxidant-containing material. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies.In a preferred embodiment, a substance comprising a filler material and a solid oxidant, preferably an admixture of particulates, is coated onto at least a portion of the solid oxidant-containing material. Such a technique is particularly advantageous for forming relatively thick reaction product layers which might not otherwise develop to the desired thickness using the original "directed growth" embodiment. In a particularly preferred embodiment, the solid oxidant and the solid oxidant-containing material have the same chemical composition, and the filler material and the reaction product have the same chemical composition.

    摘要： There is provided a method for producing a self-supporting ceramic composite comprising (1) a ceramic matrix obtained by oxidation of an aluminum zinc alloy to form a polycrystalline oxidation reaction product of the metal with an oxidant, and (2) one or more fillers embedded by the matrix. The metal alloy and permeable mass of filler having at least one defined surface boundary are oriented relative to each other so that formation of the oxidation reaction product will occur into said mass of filler and in a direction towards said defined surface boundary. On heating the metal to a first temperature above its melting point but below the melting point of said oxidation reaction product to form a body of molten parent metal, the molten metal reacts with said oxidant to form said oxidation reaction product which infiltrates said mass of filler to said defined surface boundary. The resulting infiltrated mass is heated to a second temperature in order to remove or oxidize at least a substantial portion of one or more residual non-oxidized metallic constituents from or in said infiltrated mass without substantial formation of said oxidation reaction product beyond said defined surface boundary, thereby producing a self-supporting ceramic composite.
