| 20100167907 | METHOD FOR MANUFACTURING TRANSPARENT POLYCRYSTALLINE ALUMINUM OXYNITRIDE - The present invention relates to a method of manufacturing a transparent polycrystalline aluminum oxynitride. Aluminum oxynitride manufactured by prior art methods has a great number of porosities therein and thus has low transparency. The present invention is directed to solving such a problem. In the method of manufacturing aluminum oxynitride of the present invention, a sintering additive added to a source powder includes less than 0.5 wt. % MgO. Further, the source powder is presintered at 1550° C. to 1750° C. so that a relative density becomes 95% or more and is then resintered at 1900° C. or more so that a relative density higher than that of presintering can be accomplished. According to the present invention, a cubic-phased polycrystalline aluminum oxynitride ceramic can be obtained, wherein porosities therein are nearly eliminated and its substantial transparency becomes 95% or more. | 07-01-2010 |
| 20100331167 | Ceramics for Decorative Component and Decorative Component Using the Same - An object of the present invention is to provide ceramics for decorative component which has golden color tone and provides high-grade impression, aesthetic satisfaction and mind soothing effect, and has high mechanical properties such as hardness and toughness with less color difference. The present invention relates to a ceramics for decorative component, composed of titanium nitride-based sintered material which contains titanium nitride as a main component, wherein the titanium nitride-based sintered material contains nickel, niobium, chromium and carbon, and wherein a content of carbon is not less than 0.5% by mass nor more than 0.9% by mass. According to the ceramics for decorative component of the present invention, it is possible to have better mechanical properties such as hardness and toughness since carbon diffuses and forms solid solution with titanium nitride that accelerates the sintering process. In addition, since the black color of carbon is expected to suppress the surface color from becoming uneven through the effect of making the color a little achromatic. As a result, color difference (ΔE*ab) can be decreased so that difference in color tones is hardly felt among the decorative components. | 12-30-2010 |
