What product does Magnesium metal fire create?

Question

If u know please answer, Thanks

I only have about 33mins, please help me

Answer 1

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 both nitrogen (forming magnesium nitride), and carbon dioxide (forming magnesium oxide and carbon).

Chris M's answer is right on what a mag fire produces (we just called it all "dross" though), but I know from experience that large masses of magnesium ARE easy to ignite. I used to work in a factory that made magnesium diecast parts. All you have to do is get it to it's melting point and let air get to it, and you'll soon have yourself the brightest fire you've ever seen, and it's one of the hardest fires to put out. we ran out pots of molten AZ91D magnesium at about 1130 degrees (F), you can hit that temperature with many normal fires, and we did it on accident several times a week usually. fires like that are pretty normal in the mag casting business. Like any molten metal, hitting it with water makes it explode and spread. The best way we found to fight mag fires was to cover it with sand so it didn't spread and pretty much let it burn out on it's own on the concrete floor. Class D fire extinguishers work, but not much better than sand and they cost a lot more. There is also some product of magnesium combustion that will ignite if a small amount of water gets on it, but I don't think it is always produced in "normal" magnesium fires, sso it's probably some impurity that got mixed in during the fire.

Parts we made were the valve covers for the Dodge Viper and several types of Toyota, steering column parts for many Fords and Chrysler, GM carburator parts, Compaq laptop computer bodies, Ericsson cell phone bodies, Ford car stereo housings, brake and clutch pedal brackets, InFocus projector lens housings, and many many more products you probably are around much of the time.

They use powdered magnesium in the fireworks you see on the 4th of July, too. The colors are made by adding small amounts of other metals like copper, but the brightness is all magnesium fire.

Answer 3

Magnesium is one of the alkaline-earth metals, and is one of the most common elements in the Earth's crust. In its pure form, it is silvery white, and relatively soft. It burns in air with a brilliant white light, and for this reason is often used in flares and fireworks.

2Mg(s) + O2(g) ——> 2MgO(s)

The high temperatures reached during the combustion also allow small amounts of magnesium to react with nitrogen in the air, producing magnesium nitride:

3Mg(s) + N2(g) ——> 2Mg3N2(s)

Answer 4

road flares use it.


then theres "the good stuff"
i believe its called thermite
iron oxide, magnesium, potasium nitrate... those are the main ones at least.

Answer 5

I beleive its what a road flare is made of.
