Magnesium

In the table, magnesium is in group II of the main subgroup of the second group under atomic number 12. It is one of the most common elements of the earth's crust. Large amounts of magnesium are found in sea water .

The simple substance magnesium is a light, malleable silver-white metal .

Application area

Magnesium is the lightest structural metal with the best strength-to-weight ratio and a high degree of vibration damping. However, in its pure form, it is soft and fragile. Therefore, it is used in the form of alloys with other metals in various industries: automotive, aerospace, sports, hand tools. Also in the production of home appliances and electronics .

Magnesium is also used in ferrous and non-ferrous metallurgy .

Magnesium oxide MgO is used as a refractory material for the production of crucibles and special linings for metallurgical furnaces .

Perchlorate, Mg (ClO ₄ ) ₂ - (anhydrone) is used for deep drying of gases in laboratories, and as an electrolyte for chemical current sources with the participation of this element .

Fluoride MgF ₂ - in the form of synthetic single crystals is used in optics (lenses, prisms) .

Bromide MgBr ₂ - as an electrolyte for chemical backup current sources .

In the oil and gas industry, magnesium alloys are used to protect steel structures and main pipelines from corrosion .

Because Since the metal burns with a blinding white flame, it is widely used in military technology for the manufacture of lighting and signal rockets, tracer bullets and projectiles, and incendiary bombs .

Magnesium oxide and salts are also used in medicine in cardiology, neurology and gastroenterology.

Magnesium oxide is used in the production of cements, refractory bricks, and in the rubber industry. Magnesium peroxide is used to bleach fabrics. Magnesium sulphate is used in the textile and paper industries as a mordant for dyeing. An aqueous solution of magnesium chloride - for the preparation of magnesian cement, xylolite and other synthetic materials .
