Abstract
A porous copper body including a skeleton having a three-dimensional network structure is provided. An oxidation-reduction layer formed by an oxidation-reduction treatment is provided on a surface of the skeleton, and the average crystal grain size of an entirety including the skeleton and the oxidation-reduction layer is 5% or more of the diameter of the skeleton.
Claims12
A porous copper body, comprising:
- a skeleton having a three-dimensional network structure,
- wherein an oxidation-reduction layer formed by an oxidation-reduction treatment is provided on a surface of the skeleton,
- the skeleton is constituted by a sintered body made of a plurality of copper fibers,
- in each of the copper fibers, a diameter R is set to be in a range of 0.05 mm to 1.0 mm, and a ratio L/R of a length L to the diameter R is set to be in a range of 4 to 2500, and
- an average crystal grain size of an entirety including the skeleton and the oxidation-reduction layer is in a range of 5% to 300% of a diameter of the copper fibers in the skeleton.
