Abstract
A molded article having a small difference in thermal conductivities between a central section and a section located at an outer peripheral surface side; and a method for producing the same; wherein, a plate-shaped molded article includes an aluminum-silicon carbide composited section in which a metal including aluminum was impregnated into a silicon carbide porous body, wherein a difference in the densities, by Archimedes' principle, of a central section of the aluminum-silicon carbide composited section and of at least a portion of an outer side section located further toward the outside peripheral surface side than the central section is 3% or less.
Claims10
A plate-shaped molded article comprising an aluminum-silicon carbide composited section in which a metal comprising aluminum was impregnated into a silicon carbide porous body, wherein:
- a relative density of the silicon carbide porous body in the aluminum-silicon carbide composited section is 60-75%,
- an average thickness of the aluminum-silicon carbide composited section is 2-7 mm, and
- the aluminum-silicon carbide composited section is configured so as to have a planar view quadrangular plate shape and, when the quadrangular plate shape is divided into 25 equally divided pieces by being cut, perpendicularly to the plate surface, along lines that are parallel to one side thereof and that divide the quadrangular plate shape into five equal parts, and along lines that are parallel to a side intersecting the one side and that divide the quadrangular plate shape into five equal parts, a difference between the density, by Archimedes' principle, of a divided piece at the center and an average value of the densities, by Archimedes' principle, of the divided pieces at the four corners is 3% or less.
