Abstract

A process for the production of moldings of compressed expanded graphite includes producing three-dimensional moldings of compressed graphite expandate by bonding together two-dimensional pre-formed pieces of pre-compressed expanded graphite under the influence of pressure to provide single-piece moldings. A process for conducting, exchanging or storing heat using the moldings and a process for producing a heat storage device, are also provided.
