Nuclear fusion is a process with enormous potential for energy production, requiring materials that can withstand extreme conditions. Graphite and tungsten are candidates for plasma-facing components in fusion reactors due to their high melting points. Tungsten, with one of the highest melting points among all elements, is favored for its durability under intense heat and neutron bombardment. The study of these materials' geological behavior is essential for MaxPure., as they can be used in constructing the inner walls of fusion reactors to handle the extreme temperatures generated during fusion. This is particularly relevant for the ITER project, which aims to demonstrate the feasibility of fusion power, and where tungsten's ability to withstand up to 3422°C is critical.
