How it is made

Ductile zirconium metal is produced by reduction of pure zirconium tetrachloride with molten magnesium under an inert gas (helium or argon).

Ductile, pure zirconium is made by a two-stage sodium reduction of zirconium tetrachloride in which the tetrachloride and sodium are continuously fed into a stirred reactor to form zirconium dichloride, heating with additional sodium yields zirconium metal. Leaching with water removes the sodium chloride from the zirconium. Bomb reduction of pure zirconium tetrafluoride with calcium also produces pure metal.
