Magnesium powder (magnesiumpowder) usually refers to the powder state of the single magnesium, the appearance of silver-white powder with a metallic luster, active metal, flammable items when wet.
When burning, it produces strong white light and releases high heat. When it meets water or moisture, it releases hydrogen gas and a large amount of heat, causing combustion or explosion.
When meet chlorine, bromine, iodine, sulphur, phosphorus, arsenic and oxidising agent, it produces violent reaction, and has the danger of combustion and explosion.

Magnesium powder - Application
Used in the manufacture of pyrotechnics and flares. It is used as reducing agent, flash powder, lead alloy, desulphurising agent and purifying agent in metallurgy, and dehydrating agent in organic synthesis or organic compounds of magnesium made directly from magnesium powder.
Especially in recent years. Magnesium powder in the spraying, anti-corrosion industry in the use of more and more, in monocrystalline silicon, polycrystalline silicon, as well as metallurgical powder die-casting is also a large amount.
