Processes, systems, and apparatus for cyclotron production of technetium-99m

Abstract

A process for producing a hardened target plate coated with a molybdenum-100 metal, comprising the steps of: (i) suspending and intermixing a refined molybdenum-100 metal powder having grain sizes of less than about 10 microns, and a binder, in a polar organic solvent; (ii) inserting into the molybdate-100 mixture, a cathode plate comprising a transition metal and an anode plate comprising conductive metal; (iii) applying a potential from about 300 V to about 1,300 V to the anode plate and cathode plate; (iv) recovering the cathode plate from the molybdate-100 mixture; and (v) sintering the cathode plate at a temperature from a range of about 1,200° C. to about 1,900° C. for a period of time from about 3 h to about 8 h.
