Description and uses: this is a high end grade, both in purity and fineness (140 mesh, 105 micron) suitable for pyrotechnical uses, survivalism (fire making) as well as various inorganic and organic synthesis.
With many powdered strong oxidisers magnesium powder forms flash powders (reaction temperature reached is so high reaction products instantly vapourise).
In organic chemistry it's mainly used in Grignard reactions. This high grade is perfectly suitable as a Grignard substrate.
As a reducing agent in inorganic chemistry it reacts with anhydrous fluorides much the same way aluminium powder reacts with anhydrous oxides. Among the fluorides that can be successfully reduced to lump metal (and magnesium fluoride as a by-product) are several D-block element fluorides (TiF3, ZrF4 and others), as well as UF4 and ThF4.
From a molten mixture of anhydrous manganese (II) chloride and potassium chloride, slowly added magnesium powder precipitates pure manganese metal (a laboratory preparation method of manganese metal).
Magnesium is also a very powerful reducing agent in aqueous conditions.
