In today’s world, magnesium is used more extensively than one might think. Humanity learned about it relatively recently, at the end of the 17th century, but since then, it has come up with hundreds of uses. It is found everywhere, from some household appliances to cars! This metal is so widespread because of its properties combined with its prevalence on Earth.
- It gets its name from the mineral magnesite, which is high in magnesium. Magnesite is so called because it was discovered near the ancient Greek city of Magnesia.
- Magnesium is like silver in appearance, being also a light, silvery metal which gives good yield to forging and other processing.
- Magnesium sulfate was first got in 1695 by isolating it from salt-rich mineral water.
- One of the magnesium sulfates in the past was called "epsom salt. This bitter powder was used as a laxative.
- More magnesium is dissolved in the water of the seas and oceans than is found as deposits on land. And in salt lakes there is even more.
- China is now the world’s number one producer of this metal, and it produces more of it than all other countries put together. But at the end of the XX century, the United States held the lead with over 45% of world production.
- On average, about 19.5 kilograms of magnesium per 1 ton of soil in the Earth’s crust. This mineral is among the most abundant on our planet.
- The purity of processed magnesium is 99.999% and higher. There are practically no impurities in it at all.
- The surface of magnesium is always covered by a firm oxide film. If heated to about +600 degrees, the film will be destroyed and the metal itself will burn in a dazzling white flash.
- Magnesium burns so brightly that it is impossible to look at these flames without dark glasses - you can get retinal burns.
- Magnesium is used in the production of many ultralight alloys, which is why it is widely used in aircraft construction and aviation.
- In today’s world, not only minerals are used to produce this metal but also sea water.
- Another application of the metal is in the production of high-capacity batteries, or, simply, batteries.
- Magnesium is a vital element that is found in all body tissues and is necessary for normal cell function. It is involved in most metabolic reactions, in regulating nerve impulse transmission, and in muscle contraction.
- Magnesium is one of the important biogenic elements; it is found in significant amounts in the tissues of animals and plants.
- It is the ninth most abundant element in the universe. It is produced in dying stars from the sequential addition of three helium nuclei to the carbon core. When such stars go supernovae, most of the magnesium is ejected into the interstellar medium, where it serves as raw material for the formation of new stars.
- The daily allowance of magnesium for an adult is about 300 mg for women and 400 mg for men. However, the body only absorbs about 30% of it.
