Abstract
Abstract A composite electrode for MHD conversion ducts is constituted by identical elements in juxtaposed relation, each main element being made up of ceramic blocks assembled in a metallic support and each block being essentially made up of a current-collecting ceramic element which is placed between two heat-insulating ceramic elements. The electrode is unaffected by the corrosive action of molten alkali-metal seed material within the duct.
