Abstract: 888,884. Separating isotopes of alkali metals. COMMISSARIAT A L'ENERGIE ATOMIQUE. Dec. 22, 1958 [Dec. 20, 1957], No. 41380/58. Class 41. Isotopes of alkali metals, especially lithium, are separated by electrolysing alkali metal nitrate which flows counter-current to cation migration, and at a speed intermediate the speeds of the two isotopes to be separated, the metal at the cathode being reconverted to nitrate by admission of nitric acid. A suitable apparatus comprises a block of steatite 1, Fig. 1, having a deep longitudinal channel 2 cut therein ending in a cathode compartment 3 and an anode compartment 4, each communicating with the channel through oblique small passages 5. The whole is mounted in a glass tube furnace 8, provided with a suction duct 11 to remove vapours and gases. The anode 7 is platinum, the cathode 6 comprises a tube 15 carrying a basketcarrying fragments of a refractory steel. In operation, fused lithium nitrate at about 280‹ C. is introduced into the cathode compartment and flows through the channel 2 which has a thin layer of crushed statite packing 27 which prevents convention currents; the supply is cut off when the flowing salt reaches the anode compartment. A current of about 0.3A is applied and nitric acid is admitted through a tube 20 and heater 21 to form vapour passing into the cathode compartment, in sufficient quantity to convert lithium deposited at the cathode. A slight slope of about 1 in 400 is imparted to the block 1 to generate a flow of electrolyte to the anode, intermediate the speeds of Li 6 and Li 7. After 72 hours the ratio of the two isotopes is 11.95 at the anode, and 10.8 at the cathode as compared with 11.35 in the original electrolyte. The single channel 2 may be multipled and may be in the form of a coiled passage. The steatite packing 27 may be replaced by zirconia or P.T.F.E. of suitable grain size.
