Magnesium

Magnesium is an alkaline earth metal and the seventh most abundant element in the Earth's crust. It is the 11th most abundant element by mass in the human body; its ions are essential to all living cells, where they play a major role in manipulating important biological polyphosphate compounds like ATP, DNA, and RNA. It is also the metallic ion at the center of chlorophyll, and is thus a common additive to fertilizers. Magnesium compounds are used medicinally as common laxatives, antacids, and in a number of situations where stabilization of abnormal nerve excitation and blood vessel spasm is required. The main applications of magnesium are, component of aluminium alloys, in die-casting, to remove sulfur in the production of iron and steel, the production of titanium in the Kroll process. Magnesium, in its purest form, can be compared with aluminium, and is strong and light, so it is used in several high volume part manufacturing applications, including automotive and truck components. The second application field of magnesium is electronic devices. Because of low weight, good mechanical and electrical properties, magnesium is widely used for manufacturing of mobile phones, laptop computers, cameras, and other electronic components. Magnesium's high burning temperature makes it a useful tool for starting emergency fires during outdoor recreation. Other uses include flash photography, flares, pyrotechnics and fireworks sparklers. It is also used in the form of turnings or ribbons, to prepare Grignard reagents, which are useful in organic synthesis.

Magnesium Oxide

Magnesium oxide is a mineral that occurs naturally as periclase and is a source of magnesium. It is one of the raw materials for making Portland cement in dry process plants. It is an efficient moisture absorbent used by many libraries for preserving books. In medicine, magnesium oxide is used for relief of heartburn and sore stomach, as an antacid, magnesium supplement, and as a short-term laxative. It is also used to improve symptoms of indigestion. It is used as an insulator in industrial cables, as a basic refractory material for crucibles and as a principal fireproofing ingredient in construction materials. It is used as a reference white color in colorimetry, owing to its good diffusing and reflectivity properties. It may be smoked onto the surface of an opaque material to form an integrating sphere. It is also used as a protective coating in plasma displays.

Mercury

Mercury is the only metal that is liquid at standard conditions for temperature and pressure. It is used primarily for the manufacture of industrial chemicals or for electrical and electronic applications. It is used in some thermometers, especially ones which are used to measure high temperatures. A still increasing amount is used as gaseous mercury in fluorescent lamps, while most of the other applications are slowly phased out due to health and safety regulations and is in some applications replaced with less toxic but considerably more expensive Galinstan alloy. Mercury and its compounds have been used in medicine, although they are much less common today than they once were, now that the toxic effects of mercury and its compounds are more widely understood. The element mercury is an ingredient in dental amalgams. Mercury, as thiomersal, is widely used in the manufacture of mascara. The largest use of mercury in the late 20th century was in the mercury cell process where metallic sodium is formed as an amalgam at a cathode made from mercury; this sodium is then reacted with water to produce sodium hydroxide. Historically, mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. RoHS bans mercury from certain electrical and electronic products, and limits the amount of mercury in other products to less than 1000 ppm.

Mesitylene

Mesitylene is an aromatic hydrocarbon with three methyl substituents attached to the benzene ring. It is prepared by distillation of acetone with sulfuric acid or by trimerization of propyne in sulfuric acid, which, in both cases, acts as a catalyst and dehydrating agent. It is commonly used as a solvent in research and industry. In the electronics industry, mesitylene has also been used as a developer for photopatternable silicones due to its solvent properties. It is also a major urban volatile organic compound which results from combustion. It plays a significant role in aerosol and tropospheric ozone formation as well as other reactions in atmospheric chemistry.
