Magnesium
Description: |
|
| Magnesium is an alkaline earth metal and the seventh most abundant element in the Earth’s crust. It is the 11th most abundant element by mass in the human body; its ions are essential to all living cells, where they play a major role in manipulating important biological polyphosphate compounds like ATP, DNA, and RNA. It is also the metallic ion at the center of chlorophyll, and is thus a common additive to fertilizers. Magnesium compounds are used medicinally as common laxatives, antacids, and in a number of situations where stabilization of abnormal nerve excitation and blood vessel spasm is required. The main applications of magnesium are, component of aluminium alloys, in die-casting, to remove sulfur in the production of iron and steel, the production of titanium in the Kroll process. Magnesium, in its purest form, can be compared with aluminium, and is strong and light, so it is used in several high volume part manufacturing applications, including automotive and truck components. The second application field of magnesium is electronic devices. Because of low weight, good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop computers, cameras, and other electronic components. Magnesium’s high burning temperature makes it a useful tool for starting emergency fires during outdoor recreation. Other uses include flash photography, flares, pyrotechnics and fireworks sparklers. It is also used in the form of turnings or ribbons, to prepare Grignard reagents, which are useful in organic synthesis. | |
