Anode and cathode of identical shape and material were suspended above a ThO2 powder layer in a beaker in atmospheric pressure at room temperature to obtain active deposits containing ThB etc. on the cathode. The items of experiment were:
(1) Material of electrode plates: Al, Ti, Ni, Zn, Cd and Pt, both bare and with active charcoal powder coating
(2) Applied D.C. potential, 0100 V.
(3) Distance between the electrodes was varied
(4) Height of electrode above ThO2 layer was varied
(5) Surface area of electrode plate was varied
(6) Surface of spreaded ThO2 layer was varied
(7) Duration of electro-deposition was varied
(8) Thickness of ThO2 powder layer was varied
The active deposit was examined radiochemically.
