ELECTROLYTIC METHOD OF MANUFACTURING MOLYBDENUM TARGETS FOR OBTAINING TECHNETIUM ISOTOPES Russian patent published in 2024 - IPC G21G4/08 

Abstract RU 2811084 C1

FIELD: radiopharmaceuticals.

SUBSTANCE: invention can be used to obtain technetium isotopes used to form diagnostic radiopharmaceuticals for the studies of the brain, heart, thyroid gland, lungs, liver, gall bladder, kidneys, skeletal bones, blood, tumor diagnostics, as well as in nuclear technologies. An electrolytic method of the manufacture of molybdenum targets for the production of technetium isotopes involves the electrodeposition of molybdenum from an electrolyte. Electrodeposition of molybdenum is performed from a eutectic melt of NaCl-KCl with the addition of MoCl3, with a Mo content in the said melt of 5–7 wt.% in metal equivalent. The process is carried out at a temperature from 700 to 800 C and cathode current density from 0.01 A/cm2 to 0.15 A/cm2 in an inert atmosphere of argon to obtain molybdenum targets with a thickness of 0.115 to 0.346 mm.

EFFECT: invention makes it possible to obtain plastic molybdenum targets with a high current efficiency and an increased rate of molybdenum deposition without any side processes and electrolyte losses.
