Heat storage member

Abstract

A heat storage member including a substrate containing a SiC sintered body as a principal ingredient and a heat storage material configured to store and radiate heat by a reversible chemical reaction with a reaction medium or a heat storage material configured to store and radiate heat by physical adsorption to a reaction medium and physical desorption from a reaction medium. The substrate has a three-dimensional network structure including a skeleton having porosity of 1% or less. A void ratio of a void formed in the three-dimensional network structure of the substrate is ranging from 30 to 95%. The heat storage material is disposed at least in a part of a surface of the void in the three-dimensional network structure of the substrate.
