WebGraphite is the crystalline allotropic form of carbon occurs in free state in nature. It can be prepared artificially by heating a mixture of sand and coke in electrical furnace at about 3300 K. In graphite, the carbon atoms are … WebNeutron moderator. In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy. These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium ...
