Magnesium, Symbol Mg is a silvery white metal element that is relatively unresponsive. Magnesium is one of alkaline earth metals in Group 2 of the Periodic Table of the Elements. The atomic number of magnesium is 12.
This metal was first separated by British chemist Sir Humphrey David in 1808 and today it is mainly obtained by electrolysis of magnesium chloride. Magnesium is malleable and has ductility when heated. In addition to bismuth, it is the lightest metal and it is stable under normal conditions. The metal is not attacked by oxygen, water or alkali at room temperature; it reacts with acid. When heated to about 800 ° C, it reacts with oxygen and emits bright white light. Magnesium melts at about 649 ° C., has a boiling point of about 1107 ° C., a specific gravity of 74, and the atomic weight of magnesium is 24.305.
Magnesium is ranked sixth in the Earth's crust. It only occurs in other elements, especially chemical bonds with mineral carnallite, dolomite and magnesite, many rock forming silicates, and sea water and brine like magnesium chloride. It is an important part of animal and plant organization
Magnesium generating compound used as a refractory and insulator by reacting a magnesium salt with sodium carbonate to produce magnesium carbonate (MgCO 3); magnesium chloride compound or magnesium chloride (MgCl 2 · 6H 2 O) Magnesium citrate (Mg 3 (C 6 H 5 O 7) 24 H 2 O) Expandable beverage; expandable beverage; magnesium salt (citric acid salt) Magnesium hydroxide (Mg (OH) 2) used as a laxative "magnesium oxide" for sugar refining in pharmaceutical manufacturing; magnesium sulfate (MgSO 4. 7H 2) O) formed by the reaction of sodium hydroxide with sodium hydroxide Well-known spy salt, magnesium oxide (MgO). It is called burned magnesia or magnesia and is used for cosmetic paper making by burning magnesium in oxygen or by acting as a thermal insulator by heating magnesium carbonate. Filler, mild acid resistant purgative
Magnesium in alloy form has considerable tensile strength. If brightness is an important factor use metal: alloyed with aluminum or copper
At the same time, the nanocomposite coating has multiple functions for improving the interface properties of magnesium (Mg) alloys for bone implant applications, such as controlling the decomposition rate of Mg substrates, improving bone cell function, and providing drug delivery capability I will provide a. However, the effective use time of nanocomposite coatings may be limited as they release prematurely from Mg-based substrates. Therefore, the aim of this research is to solve the delamination problem of nanocomposite coating, to improve coating properties, to reduce decomposition of Mg substrate, thereby improving cell compatibility with bone marrow derived mesenchymal stem cells (BMSC) It was to do. The surface state of the substrate, the nature of the polymeric component of the nanocomposite coating, and the post-deposition treatment are important parameters contributing to the effectiveness of the nanocomposite coating to control substrate degradation and bone cell response.
With the advent of high performance magnesium based materials such as magnesium nanocomposites and magnesium nanocrystals / bulk amorphous materials (Mg - BMG), magnesium technology has recently taken a big step to respond to future applications. A processing method is created. Among these new materials, excellent properties that can not be achieved with conventional alloys have been achieved. Collaborative research is under way to understand material properties under various load / operating conditions using advanced characterization tools.
Magnesium is the metal of the 21st century. Magnesium alloys are considered one of the most versatile material selections for structural materials with energy efficiency and environmental advantages. Magnesium-based materials (alloys and composites) replace aluminum, steel and structural plastics in a variety of industrial and commercial fields such as automotive, aerospace, defense, biomedicine, sporting goods, and consumer electronics It has huge infinite possibilities. The requirement, that day's demand is to develop new magnesium-based materials with outstanding performance, but also to improve manufacturing technology.
