The chemical formula for magnesium is Mg.
Magnesium is a chemical element, the twelfth element in the periodic table, having an atomic number of 12 and an atomic mass of 24.305.Magnesium is a silvery-white metal that oxidizes readily in the air to form a dense oxide film.
Magnesium exists in nature mainly in the form of compounds such as magnesium oxide (MgO) and magnesium hydroxide (Mg(OH)2). These compounds have a wide range of applications in industry and daily life. Magnesium oxide is a common refractory material, while magnesium hydroxide is used in the manufacture of pharmaceuticals and cosmetics.
Magnesium is chemically active and reacts readily with many elements and compounds. These include reactions with oxygen, water, carbon dioxide and nitrogen. Magnesium reacts with oxygen to form magnesium oxide, with water to form magnesium hydroxide, with carbon dioxide to form magnesium carbonate, and with nitrogen to form magnesium nitride.
Magnesium has important physiological functions in the human body. It is an important component of human bones and teeth and is involved in many biochemical reactions. Magnesium deficiency may lead to muscle cramps, cardiac arrhythmias, and other health problems.
Applications of magnesium:
1. Aerospace: Magnesium alloys can significantly reduce the weight of airplanes, improve fuel efficiency, and reduce tailpipe emissions, which improves the performance of airplanes. Therefore, many airplanes and spacecraft are made of magnesium alloy.
2, the automotive field: magnesium alloy has been widely used in developed countries for automotive instrument panels, seat brackets, transmission shells, directional manipulation system components, hood covers, doors, engine blocks, frames and other parts. With magnesium alloy manufacturing automobile parts, can significantly reduce the weight of the car, reduce fuel consumption, reduce exhaust emissions, improve the integration of parts and improve the flexibility of automobile design.
3, medical equipment: magnesium also has a wide range of applications in the medical field. It can be used as a therapeutic drug for cardiovascular disease, cancer and other diseases.
4, electronic equipment: magnesium also has a wide range of applications in the field of electronic equipment. For example, many cell phones, tablet computers and other portable equipment shells are made of magnesium alloy.
5, construction field: magnesium also has a wide range of applications in the field of construction. For example, magnesium can be used to manufacture building templates, brackets, decorative panels and so on.
