Abstract: A dense ceramic sintered body is appropriately manufactured. A manufacturing method for the ceramic sintered body includes: a step of performing heat treatment on a ceramic green body as a green body of ceramic powder under a first condition; a step of performing heat treatment, under a second condition with a higher pressure than the first condition, on the ceramic green body subjected to the heat treatment under the first condition; and a step of performing heat treatment, under a third condition with a higher pressure than the second condition, on the ceramic green body subjected to the heat treatment under the second condition to manufacture the ceramic sintered body.

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.
