Synthetic Graphite Powder (Nuclear Grade)

Nuclear graphite is any grade of graphite, usually synthetic graphite, specifically manufactured for use as a moderator or reflector within a nuclear reactor. Graphite is an important material for the construction of both historical and modern nuclear reactors, due to its extreme purity and its ability to withstand extremely high temperatures. Graphite has also recently been used in nuclear fusion reactors as well, such as the Wendelstein 7-X. As of experiments published in 2019, the use of graphite in elements of the stellarator's
