Abstract: A method for molding a ceramic material includes: mixing a ceramic powder, a resin, a curing agent and a solvent to obtain a raw material slurry for a ceramic material; injecting the raw material slurry into an elastic container; curing the resin in the raw material slurry injected into the elastic container to form a molded body having a desired shape; and demolding the molded body from the elastic container.

Abstract: The present invention relates to a method of producing a SiC—Si composite component. The method includes preparing a first molded body containing SiC particles by a 3D printing method, wherein the first molded body has a first average pore diameter M1;

forming a second molded body, in which the first molded body and a dispersion containing carbon particles are brought into contact so that the pores are impregnated with the carbon particles, wherein the carbon particles have a secondary particle having an average particle diameter M2, and the carbon particles satisfy the following formula:




M2≤M1/10; and

forming a SiC—Si composite component by carrying out that the second molded body is impregnated with a metallic si and is reactively sintered;
wherein the content of Si is in the range of 5% by mass to 40% by mass in the SiC—Si composite component.

Abstract: The present invention relates to a light-transmitting ceramic sintered body which contains air voids having pore diameters of 1 μm or more but less than 5 μm at a density within the range of from 10 voids/mm3 to 4,000 voids/mm3 (inclusive), while having a closed porosity of from 0.01% by volume to 1.05% by volume (inclusive). With respect to this light-transmitting ceramic sintered body, a test piece having a thickness of 1.90 mm has an average transmittance of 70% or more in the visible spectrum wavelength range of 500-900 nm, and the test piece having a thickness of 1.90 mm has a sharpness of 60% or more at a comb width of 0.5 mm.
