·Product Chemical and Physical property
|Chemical Composition,%||Physical Properties|
Magnesium is a highly flammable metal, but while it is easy to
ignite when powdered or shaved into thin strips, it is difficult to
ignite in mass or bulk. Once ignited, it is difficult to
extinguish, being able to burn in nitrogen (forming magnesium
nitride), carbon dioxide (forming magnesium oxide and carbon) and
water (forming magnesium oxide and hydrogen). This property was
used in incendiary weapons used in the firebombing of cities in
World War II, the only practical civil defense being to smother a
burning flare under dry sand to exclude the atmosphere. On burning
in air, magnesium produces a brilliant white light which includes
strong ultraviolet. Thus magnesium powder (flash powder) was used
as a source of illumination in the early days of photography.
Later, magnesium ribbon was used in electrically ignited flash
bulbs. Magnesium powder is used in the manufacture of fireworks and
marine flares where a brilliant white light is required. Flame
temperatures of magnesium and magnesium alloys can reach 3,100 °C
(3,370 K; 5,610 °F),[although flame height above the burning metal
is usually less than 300 mm (12 in). Magnesium may be used as an
ignition source for thermite, an otherwise difficult to ignite
mixture of aluminium and iron oxide powder.
