Some special isotope material is usually used in nuclear experiments. It can be served as ion beam or target. When new superheavy nuclide ^265Bh (Z=107) is synthesized, a reaction of ^243Am target with ^26Mg ion beamis selected to produce new isotope ^265Bh. The preparation and production of this rare and extremely expensive isotope ^26 Mg used for ion beam substance will be a key problem in synthesizing experiment of 265Bh. Theavailable chemical form of isotope ^26Mg in commercial product usually is oxide or other compound, which are not required in our experiment. They need to be transformed to metal form as a proper working substance in ion source.
