A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.

A method for manufacturing a ceramic article including (i) a step of irradiating a powder mainly containing a ceramic material with an energy beam to sinter or melt and solidify the powder into a solidified portion, wherein the step is repeated a predetermined number of times to sequentially bond the resulting solidified portions together to obtain a ceramic modeling object, (ii) a step of allowing the shaped ceramic object to absorb a metal component-containing liquid that contains inorganic particles containing a metal element; and (iii) a step of heating the shaped ceramic object that has absorbed the metal component-containing liquid.

A ceramic body for dental prosthesis can suppress a variation in quality in the sole ceramic body for dental prosthesis due to expansion of its diameter. The ceramic body for dental prosthesis is made of a ceramic material, is shaped to have a circular planar shape and a disk-like external shape, and has a diameter of 50 mm or more. The method for manufacturing this ceramic body for dental prosthesis includes: preparing a ceramic material; shaping the ceramic material by press shaping or by a machine tool; temporarily sintering the ceramic material at a temperature from a sintering temperature that provides theoretical density −700° C. or more to the sintering temperature −100° C. or less; and shaping the ceramic material to have a circular planar shape and a disk-like external shape so as to prepare the ceramic body for dental prosthesis having a diameter of 50 mm or more.

A silicon nitride substrate includes silicon nitride and magnesium, in which when a surface of the silicon nitride substrate is analyzed with an X-ray fluorescence spectrometer under the specific Condition I, XB/XA is 0.8 or more and 1.0 or less.

An electrolyte sheet for solid oxide fuel cells includes a ceramic plate body containing a cubic zirconia sintered material, wherein, with the ceramic plate body being defined to have nine portions including an outer peripheral portion and a central portion, ceramic grains in each of the nine portions have a median size D.sub.50 of 1.0 μm to 4.0 μm, and a maximum median size D.sub.50 of the ceramic grains among the nine portions is 1.0 to 1.3 times a minimum median size D.sub.50 of the ceramic grains among the nine portions.

A lithography based method for the manufacture of diamond composite materials in which green bodies are prepared by a layer-by-layer construction with resulting green bodies de-bound and sintered to achieve a dense high hardness material.

A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.
