Provided is a technique to manufacture an additive manufactured fired body in which the occurrence of deformation or the like is suppressed at a high level. Provided is a method for manufacturing an additive manufactured fired body, the method including a manufacturing step of manufacturing an additive manufactured object by using an additive manufacturing powder, and a firing step of obtaining the additive manufactured fired body by firing the additive manufactured object. In the manufacturing step, a supporter 20 that supports the additive manufactured object 10 is shaped together with the additive manufactured object 10 so as to surround the additive manufactured object 10 by using the additive manufacturing powder.

A method of constructing a skin assembly comprises forming a first skin panel and a second skin panel; removing material from the first skin panel and the second skin panel, respectively, to form one or more first fingers and one more second fingers. The method also comprises joining the first skin panel and the second skin panel such that the first skin panel and the second skin panel define a plurality of staggered expansion gaps therebetween.

A module and a process for forming a monolithic substantially closed-porosity silicon carbide fluidic module having a tortuous fluid passage extending through the module, the tortuous fluid passage having an interior surface, the interior surface having a surface roughness in the range of from 0.1 to 10 m Ra. The process includes positioning a positive fluid passage mold within a volume of silicon carbide powder, the powder coated with a binder; pressing the volume of silicon carbide powder with the mold inside to form a pressed body; heating the pressed body to remove the mold; and sintering the pressed body.

An electrostatic chuck includes a ceramic top plate layer made of a beryllium oxide material, a ceramic bottom plate layer made of a beryllium oxide material, a ceramic middle plate layer disposed between the ceramic top plate layer and the ceramic bottom plate layer, an electrode layer disposed between the ceramic top plate layer and the ceramic middle plate layer, and a heater layer disposed between the ceramic middle plate layer and the ceramic bottom plate layer. The electrode layer joins and hermetically seals the ceramic top plate layer to the ceramic middle plate layer, and the heater layer joins and hermetically seals the ceramic middle plate layer to the ceramic bottom plate layer.

The ceramic structure includes a first layer containing a first crystal particle and a second layer positioned on the first layer and containing a second crystal particle. The first crystal particle and the second crystal particle contain at least one metal element selected from the group consisting of Al, Si, Ti, Cr, Zr, and Y, and at least one non-metallic element selected from the group consisting of N, C, and B. The first crystal particle and the second crystal particle are identical compounds. When a half-width of a peak of a Miller index of a maximum intensity of the first crystal particle in an X-ray diffraction of the first layer is W1 and a half-width of a peak same as that of the Miller index of the second crystal particle in an X-ray diffraction of the second layer is W2, 9W1>W2>W1 is satisfied.
