Uranium processing - Conversion to plutonium | Britannica

Like uranium, metallic plutonium is usually obtained by high-temperature reduction of a halide salt (plutonium tetrafluoride or plutonium trifluoride) with calcium metal. Much use is also made of the so-called direct oxidation-reduction process, whereby PuO 2 is reduced with calcium metal to plutonium metal and a calcium oxide slag:
