Application: | Magnesium (powder) can be used as a reducing agent to synthesize: • Titanium alloy hydride powder by the reduction of upgraded titania slag (UGS) under hydrogen atmosphere. • Ultrafine metallic iron (bcc-Fe) powders from hematite (α-Fe2O3) by ball-milling process. It can also be used as a reducing agent in ruthenium(III) complex catalyzed atom-transfer radical addition (ATRA) and cyclization (ATRC) reactions. Magnesium does not generate free radicals but it generates and regenerates the catalytically active ruthenium(II) species. |
