hello biggrin.gif ,

Magnesium is a highly versatile metal favoured for its light weight and high strength-to-weight ratio. It is non-toxic, has excellent machining qualities, and exhibits a capacity to dampen and absorb vibration and electromagnetic waves.

Magnesium.com recently announced the introduction of one-piece, forged magnesium wheels for street use in North America.

if you have some interestes aboout magnesium there some news from October:
This month's issue features an update on Advanced Magnesium
Technologies and their recent contract with a pre-eminent
Chinese Manufacturer and their leadership role in magnesium
research and development. Kobe Steel, Magnesium and Aluminum
announced an increase in sales and expects magnesium sales to
continue to rise. Also profiled is an overview of the Tonsberg
Magnesium Group acquisition of Zitzmann Drukguss and the Ukrainian
magnesium facility Kalusj Magniy. September magnesium prices
and industry events for October are listed.magnesium.com

But that is not all!

If you light magnesium spoon/flakes/etc. on fire, it will burn with a passion:P

In a UFO book in the 60's some recovered debris from a UFO was of things made from magnesium. But once magnesium starts burning, it burns with a blinding white light and even water does not not stop it from burning. How could it be stabilised to prevent such an accident occuring? A coating of some kind? An alloy?

2 Mg + O2 = 2 MgO
Water does stop it from burning.

Proveit. To quote:

Hazards
Work in a well-ventilated area. Do not look directly at burning magnesium. The reaction will release some fine particles of magnesium and magnesium oxide into the air. This can be harmful if inhaled in large quantities. Neither a carbon dioxide nor a water fire extinguisher will put out a magnesium fire. Should a fire result, the best thing to do is to let it burn out on its own, provided it is not growing out of control. In that case call the fire department.

The correct equation:

Mg + H2O = MgO + H2.

Lots of free hydrogen. That's why you don't use water to put out burning magnesium.

I remember being told that there was a special powder which was used to put out magnesium fires though I would have thought that a bucket of sand would do the job?
