Magnesium oxide

Magnesium oxide (MgO) – white hydroscopic solid minerals which meet in the nature in the form of a periclase and are a magnesium source.

Receiving magnesium oxide is possible when roasting minerals of magnesite and dolomite.

In vitro receiving magnesium oxide happens by magnesium carbonate processing by magnesium chloride to lime and the subsequent thermal treatment.

Properties of magnesium oxide

Magnesium oxide – inodorous white powder soluble in acid and ammonia and insoluble in alcohol.

Molecular formula of magnesium oxide – MgO, molar weight – 40,3044 g/mol, density – 3,58 g/cm ³, melting temperature – 2852 °C, 3125 K, 5166 °F, boiling temperature – 3600 °C, 3873 K, 6512 °F, solubility in water – 0,0086 g / 100 ml (30 °C).

Magnesium oxide use

In traditional medicine magnesium oxide is used as mineral additive for prevention and treatment of deficit of magnesium in blood. Magnesium is very important component for normal functioning of cells, a nerve, muscles, bones and heart.

As a rule, well balanced diet provides the normal content of magnesium in blood. However as furosemide and a hydrochlorothiazide, gastrointestinal diseases, bad food, alcoholism and a diabetes mellitus lead reception of such medicines to development of deficit of magnesium in an organism.

Antiacid properties of magnesium oxide help at a gastric disturbance, a hyperoxemia of a stomach and heartburn, neutralizing acidity of a stomach. Also magnesium oxide is applied as laxative at treatment of stomach ulcer, a duodenum and stones of calcium oxalate in kidneys.

Magnesium oxide is a part of medicines and nutritional supplements which effect is directed to completion of deficit of magnesium in an organism. Medicine on the basis of magnesium oxide is taken inside, it is desirable during food to exclude a gastric disturbance and diarrhea. It is necessary to accept drugs regularly at the same time, for obtaining the maximum advantage. The dosage depends on the state of health and reaction to treatment.

The magnesium oxide surplus in blood can result in serious side effects. Before accepting additives which part magnesium oxide is medical consultation as they can contain inactive components, which defiant allergic reactions is necessary.

As an industrial component magnesium oxide is used in production of paper, magnesian salts (Epsom salt), acetates, chlorides and as a component in some types of cement.

In the fiber glass industry magnesium oxide is used in processing of steel and nickel.

Magnesium oxide is a part of insulators of industrial cables as the main fire-resistant material for crucibles and as the main component in production of fire-resistant construction materials. It is widely used in heating systems as a component of heating elements of tubular designs.

The pressed crystals of magnesium oxide are used in production of optical material. They are transparent from 0,3 to 7 microns and possess a good indicator refraction 1,72 at 1 micron, and also have low cost.

Magnesium oxide is used at the recycling plants as substance capable to control solubility of radionuclides.

Also oxide magnesium it is used as a sheeting for plasma displays, and athletes use magnesium oxide powder as white topping for hands thanks to which they do not slide on apparatuses.

In the industry magnesium oxide is applied to production of rubber, synthetic rubbers and purification of oil products, and in electronic industry it is used as an abrasive for cleaning of surfaces.

In the food industry magnesium oxide is known as E530 nutritional supplement – the emulsifier which is not dissolved in water which is used in production:

• Powdered milk;
• Cream powder;
• Chocolate;
• Cocoa;
• Edible oils.

Contraindications and harm of magnesium oxide

Reception of medicines on the basis of magnesium oxide can lead to gastric disturbances and a diarrhea, serious allergic reactions (rash, an itch and hypostases in particular in a face, language and a throat), to urticaria, severe dizzinesses, spasms, differences of mood, weakness, nausea, vomiting, fatigue and trouble breathing.

Drugs on the basis of magnesium oxide with care are appointed at a disease of kidneys, during pregnancy and in the period of a lactation.

Medicines in the form of liquids and powders which part magnesium oxide is also may contain sugar and sweetener aspartame. Liquids can also contain alcohol. They with caution should be taken at such diseases as diabetes, alcohol addiction, liver diseases, a fenilketonuriya and at any other diseases which treatment demands restriction of these substances in a daily diet.

Reception of magnesium oxide is contraindicated at the use of cellulose of sodium of phosphate, digoxin and polistirolsulfanat of sodium.

Magnesium oxide can neutralize completely action of such medicines as:

• Tetracyclines (demeclocycline, doxycycline, minocycline and tetracycline);
• Bisfosfonata (алендронат);
Thyroid
• gland drug (left thyroxine);
• Antibiotics (ciprofloxacin, levofloxacin).

Uses of magnesium oxide can cause slight irritations of skin and eyes. Inhalation of powder of magnesium oxide can cause irritation of a nose and throat, and steam inhalation of magnesium oxide can cause a condition of the foundry fever accompanied with such symptoms as metal smack in a mouth, irritation of a throat, dry cough, increase in leukocytes in blood, a fever and weakness of muscles.
