A direct process for preparing zirconium, Zircaloy, and orther alloys in massive form by calcium reduction is described. Zirconium tetrafluoride is reduced in the presence of the alloying metals. The yield is excellent even if no booster is used. However, it is necessary to use calcium with a low oxygen content to obtain ductile ingots. Details on a method for purifying zirconium metallothermic reactions are discusssd. Some experimental techniques are discussed. (auth)
