Fusion reactors require special materials that can withstand the incredibly harsh environment inside the reactor. Technical / advanced ceramics can provide the properties required to withstand these harsh environments. There are a combination of materials required in a reactor; 1. Structural materials form the main body of the reactor and need to be very strong and resistant to the intense heat and radiation. Some examples are steels modified to be less radioactive when bombarded by neutrons, copper, titanium, vanadium alloys and fiber-reinforced silicon carbide. 2. Plasma-facing materials line the inner wall of the reactor vessel and are in close proximity to the hot plasma. They need to be able to withstand high temperatures, particle bombardment, and chemical erosion. 3. Breeder blanket and heat exchange materials. Ceramics that are chemically inert and have good thermal properties include Shapal Hi M Soft, Macor, Alumina, Boron Nitride and Zirconia. 4. Magnetic confinement materials. Ceramics are suitable for cryogenic and high magnetic field applications. 5. Control, instrumentation and peripherals. Ceramics are likely to be incorporated in electrical, electronic and sensor control applications throughout the fusion systems. The choice of materials for a fusion reactor is a complex one. The best materials will depend on the specific design and related challenges of the fusion reactor which can be very different from one another.
