A method for manufacturing a ceramic plate-shaped body that efficiently manufactures a ceramic plate-shaped body having high smoothness without requiring polishing after firing. The method includes preparing an unsintered plate-shaped body, preparing a plurality of resin sheets by a resin slurry containing a spherical resin powder that is composed of a resin material being poorly-soluble in an organic solvent and burning out during firing, producing an unsintered laminate by laminating and press-bonding the unsintered plate-shaped body and the resin sheet, firing the unsintered laminate so that the unsintered plate-shaped body is sintered to form a ceramic plate-shaped body, and the ceramic plate-shaped bodies are bonded to each other with scattered fine bonding portions interposed therebetween to form a ceramic laminate, and breaking the bonding portions in the ceramic laminate so that the ceramic laminate is divided into a plurality of ceramic plate-shaped bodies.

The present invention provides a zirconia pre-sintered body that develops the preferable shade with a short firing time. The present invention relates to a zirconia pre-sintered body comprising zirconia that comprises predominantly monoclinic, and a stabilizer capable of inhibiting a phase transformation of zirconia, the zirconia pre-sintered body satisfying the following conditions: L1, a1, b1, L2, a2, and b2 are confined within predetermined ranges, L1>L2, a1<a2, and b1<b2,
where (L1,a1,b1) represent values of (L*,a*,b*) of the L*a*b* color system after sintering as measured at a first point falling within an interval of a length from one end of the zirconia pre-sintered body to 25% of the entire length of a straight line extending along a first direction from one end to the other end of the zirconia pre-sintered body, and (L2,a2,b2) represent values of (L*,a*,b*) after sintering as measured at a second point falling within an interval of a length from the other end of the zirconia pre-sintered body to 25% of the entire length of the straight line, and the values of (L*,a*,b*) after sintering show unchanging patterns of increase and decrease in a direction from the first point to the second point.

There is provided a functional layer including a layered double hydroxide. The functional layer further contains titania.

An assembly includes a first member, a second member adjacent to the first member, and an aluminum material. At least one of the first member and the second member defines at least one trench. The aluminum material is disposed within the trench and bonds the first member to the second member along adjacent faces. A spacing between the first member and the second member along the adjacent faces is less than 5 m and a surface roughness of the adjacent faces of the first and second ceramic members is between 5 mm and 100 nanometers.

The disclosure relates to microchemical (or microfluidic) apparatus as well as related methods for making the same. The methods generally include partial sintering of sintering powder (e.g., binderless or otherwise free-flowing sintering powder) that encloses a fugitive phase material having a shape corresponding to a desired cavity structure in the formed apparatus. Partial sintering removes the fugitive phase and produces a porous compact, which can then be machined if desired and then further fully sintered to form the final apparatus. The process can produce apparatus with small, controllable cavities shaped as desired for various microchemical or microfluidic unit operations, with a generally smooth interior cavity finish, and with materials (e.g., ceramics) able to withstand harsh environments for such unit operations.

A multilayer electronic component includes a body including dielectric layers and first and second internal electrodes alternately laminated with respective dielectric layers interposed therebetween, and first and second surfaces opposing each other in a direction by which the internal electrodes are laminated, third and fourth surfaces connected to the first and second surfaces and opposing each other, and fifth and sixth surfaces connected to the first to fourth surfaces and opposing each other; a moisture-proof layer disposed on at least one surface of anyone of the first, second, fifth, or sixth surface and containing a rare-earth oxide; a first external electrode disposed on the third surface and connected to the first internal electrodes; and a second external electrode disposed on the fourth surface and connected to the second internal electrodes.

An intermediate member is a member which is directly or indirectly sandwiched between a first object and a second object. The intermediate member includes a plate-like supporting member having a lower surface which is one main surface opposed to the first object and a plurality of ceramic blocks fixed on an upper surface which is the other main surface of the supporting member in a state of being separated from one another. Thus, in a state where the plurality of ceramic blocks are collectively held by the supporting member having relatively high shape retention, by disposing the intermediate member between the objects, it is possible to easily arrange the plurality of ceramic blocks between the objects with high positioning accuracy.

A shell and a method for processing the shell are provided. The method includes: coating a sol prepared in advance on an inner surface of a ceramic shell prepared in advance; sintering the ceramic shell coated with the sol by using a sintering process, and forming a transition layer having nano-sized micro-pores on the inner surface of the ceramic shell.
