Abstract

Uranium is produced by reacting uranium tetrafluoride with magnesium, and is preferably produced in massive form by preheating the reaction mixture, the amount of heat added being equivalent to the difference between the heat produced by reaction of the fluoride with calcium and that produced by reaction with magnesium, the uranium being thereby liberated in the molten condition. The necessary preheat is given by heating the reaction mixture to between 500 and 700 DEG C. Preferably the particle size of the fluoride is such that more than 75 per cent passes a British Standard sieve of 60 meshes per inch, more than 60 per cent passes a sieve of 80 meshes per inch, more than 50 per cent passes a sieve of 100 meshes per inch and more than 40 per cent passes a sieve of 200 meshes per inch. The magnesium preferably has a particle size not greater than that passing a sieve of 7 meshes per inch. The reaction may be carried out in a sealed container having a refractory lining such as of calcium or magnesium oxide. The reaction may be started by means of an electrically heated uranium wire extending into the mixture. Specification 796,589 is referred to.
