| 20160016853 | ZIRCONIA SINTERED BODY, AND ZIRCONIA COMPOSITION AND CALCINED BODY - A zirconia sintered body, where when cross-sectional area of each zirconia crystal-grain is calculated in image of cross section of zirconia sintered body, converted crystal-grain size of each zirconia crystal-grain is calculated based on cross-sectional area where each zirconia crystal-grain has circular cross-sectional shape, zirconia crystal-grains are classified into class of <0.4 μm, class of ≧0.4 and <0.76 μm, and class of ≧0.76 μm based on converted crystal-grain size, total cross-sectional area of zirconia crystal-grains is calculated in each of classes, and rate of cross-sectional area to total cross-sectional area of all zirconia crystal-grains whose cross-sectional area has been calculated is calculated in each class, rate of cross-sectional area of zirconia crystal-grains in class of <0.4 μm is 4% to 35%, rate of cross-sectional area of zirconia crystal-grains in class of ≧0.4 and <0.76 μm is 24% to 57%, and rate of cross-sectional area of zirconia crystal-grains in class of ≧0.76 μm—is 16% to 62%. | 01-21-2016 |
| 20160039721 | TITANIUM COMPOUND-CONTAINING CORE-SHELL POWDER AND METHOD OF MAKING THE SAME, AND TITANIUM COMPOUND-CONTAINING SINTERED BODY - A titanium compound-containing core-shell powder includes a plurality of core-shell particles, each of which includes a core body and a shell layer encapsulating said core body. The core body is electrically conductive. The shell layer includes a crystal that is selected from titanate oxides having a perovskite structure and titanate oxides having a spinel structure. The core body and the shell layer are chemically bonded to each other. | 02-11-2016 |
