摘要：A nuclear fusion reactor has a vacuum vessel enclosing the plasma. The vessel
has a reactor wall exposed to the plasma particles. To improve the resistance to radiation of this reactor wall and to reduce its tendency to crack or deform because of thermal stress, the wall has heat-resisting ceramics tiles 4 metallurgically bonded by a solder material 11 to a metal body 5 providing a base and having cooling passages 12. The tiles are separated by gaps 14 and corresponding grooves 13 are provided in the metal body. The ceramics tiles 4 are preferably composed of sintered silicon carbide of high density and containing a little beryllium oxide between the boundaries of the crystal grains. A metallic intermediate layer may be interposed between the tiles and the metal body, this having an intermediate coefficient of thermal expansion.
