With the reduction of the relatively strong, can be reacted with boiling water to release hydrogen, combustion can produce a blinding white light, and magnesium fluoride, hydrofluoric acid and chromic acid did not work, nor by caustic erosion, but easily dissolved in organic and inorganic acid, magnesium can be directly combined with nitrogen, sulfur and halogen, organic chemistry the drugs and magnesium containing hydrocarbons, aldehydes, alcohols, phenols, amines, grease and oil, most only slight or no effect. But and halogenated hydrocarbons in anhydrous conditions are more severe reactions (generating Grignard reagent) magnesium and carbon dioxide reacts with carbon dioxide, so magnesium burning cannot fire extinguisher. Magnesium can react with N2 and O2, so the combustion of magnesium in the air, the burning of brilliant white light, heat, white solid. Changes in vinegar to emit bubbles, floating on the surface of vinegar, gradually disappear. Some fireworks and flares contain magnesium, magnesium is the use of combustion in the air can emit dazzling light of nature.
Medical use: treatment of magnesium deficiency and spasticity.
Use: to inject a few hours before strenuous exercise, or after strenuous exercise to make up for the loss of magnesium.
Gymnasts often use magnesium carbonate to increase friction. (MgCO3)
Medical treatment: if the injection of magnesium salt too fast, will cause fever and general malaise. Most of the non metal magnesium with acid and metal reaction; can direct synthesis of magnesium hydride with hydrogen under high pressure; magnesium and halogenated hydrocarbon or halogenated aromatic hydrocarbons synthesis of Grignard reagent, widely used in organic synthesis. Magnesium has obvious tendency to form coordination compounds. Magnesium is an important material in the aviation industry, magnesium alloy used in the manufacture of aircraft airframe and engine components; magnesium is also used to make photographic and optical instruments; non structural applications of magnesium and its alloys are wide; magnesium as a strong reducing agent, also used in titanium, zirconium, beryllium, uranium and hafnium production. Magnesium is a good light structural material, which is widely used in industry, such as aerospace, aviation, automobile and instrument. A supersonic aircraft with about 5% magnesium alloy components, a missile generally consume between 100 to 200 kg magnesium alloy. Magnesium is other alloys(especially Aluminum Alloy) the main component, which is matched with other elements can make Aluminum Alloy heat treatment; nodular cast iron with magnesium spheroiditic agent; and some metal (such as titanium and zirconium) production and use of magnesium as reductant; magnesium is composed of combustion bomb and flares no lack of material; magnesium is an essential ingredient of fireworks festival; magnesium is the nuclear industry structure on the materials or packaging materials; magnesium fertilizer can promote the absorption and utilization of phosphorus in plants, plant growth tends to stagnate in magnesium deficiency. Magnesium is one of the basic materials in people is life.
