History Of Discovery Of Magnesium

- Jan 28, 2019 -

The first confirmation of magnesium is an element of Joseph Black, in Edinburgh (UK) in 1755. He identified the lime (calcium oxide, CaO) in the magnesia (Magnesium Oxide, MgO), but both are similar to the carbonate by heating, magnesite and stone.

Grey stone to make. Another kind of magnesium ore called sepiolite (magnesium silicate), in 1799 by the Thomas Henry report, he said the ore more for the production of pipe in Turkey.

 

Not pure magnesium metal in 1792 by Anton Rupprecht for the first time in preparation, he heating and charcoal magnesia mixture. Pure but very small amounts of magnesium metal were prepared in 1808 by Humphry Davy electrolytic Magnesium Oxide. However, Antoine-Alexandre-Brutus Bussy, a French scientist, used sodium chloride and potassium to produce a considerable amount of magnesium in 1831, after which he began to study its properties.

 

Many centuries ago, the ancient Romans believed that the "magnesia" (a white magnesium salt produced in the Magnesia region of Greece, hence the name of magnesium) was able to treat a variety of diseases. Until 1808, the British chemist David (mg) by electrolysis from the method of separating magnesium element. In the early 30s of the world, E.V and his colleagues used mice and dogs as experimental animals for the first time to systematically observe the effects of magnesium deficiency on MoCollum. In 1934, for the first time, a small number of people reported a lack of magnesium on the basis of different diseases. Magnesium is an essential element of the human body. F and colleagues reported a case of magnesium depletion due to alcohol abuse and magnesium free intravenous infusion at the beginning of the 50s. Healthy people generally do not produce magnesium deficiency, but more and more clinical diseases have been found to be related to magnesium depletion.

Magnesium is one of the ten elements most widely distributed in nature (eighth mg is abundant in the earth is crust element in quality, accounting for about 2% of the more than and 9 is also the first element in the universe. ), but because it is not easy to restore from the compound into elemental state, so the delay has not been found.

 

Long time, chemists will obtain from containing magnesium carbonate magnesite calcined magnesium oxide magnesia as indivisible substance. In 1789, Lavoisier published a list of elements in it. In 1808, David succeeded in making calcium, using the same method and successfully made magnesium. Since then mg was identified as an element and was named magnesium, the element symbol was Mg. Magnesium comes from the Greek city of Magnesia MAG Silesia, because in this city produced near Magnesium Oxide, known as magnesia alba, a white Magnesium Oxide. However, the name of magnesium magnesium is easily confused with manganese is name manganum, although some people have made changes, but has been used. In order to avoid confusion, manganese English name changed to Manganese.
