Abstract

There is disclosed a process for the production of a ceramic heat-retaining brick based on olivine which comprises shaping and drying a mixture of granular material and a binding agent. The granular material includes powdered iron having a particle size of less than 0.1 mm in an amount of between 5 and 20% by weight of the brick. The brick is subsequently burnt in an oxidizing atmosphere and the powdered iron is substantially converted to iron oxide.
