the basic situation of magnesium
Magnesium is a chemical element, its chemical symbol is Mg, and its atomic number is 12. Magnesium is a light metal, its density is only 2/3 of that of aluminum, its thermal stability is good, and it will release heat after combustion. Magnesium mainly exists in the form of magnesite and magnesite in nature. Metal magnesium is usually produced by electrolysis or thermal reduction in industry.
the main uses of magnesium
1. Make materials
Magnesium is a good thermal and conductive material, which is often used to make cast alloys, forged alloys and powder metallurgy products. These magnesium alloys usually have good toughness, strength and heat resistance, and are widely used in aerospace, automobile industry, machinery manufacturing and electronic instruments. In addition, magnesium is also an important material for manufacturing optical instruments.
2. Make batteries
In the charged state, magnesium has stable chemical properties and high energy storage density, and magnesium-based alloys formed with metal elements such as manganese, nickel and iron can be used as battery anode materials. Magnesium alloy batteries have been more and more widely used in recent years because of their small impact on the environment and abundant magnesium reserves.
3. Hot processing and manufacturing
Magnesium has good thermal stability and is not easy to deform, so it can be used to make structural materials for high-temperature equipment. In the process of machining, magnesium also has good cutting performance and thermal conductivity, which can be used to manufacture automobile engine parts, light vehicles and so on.
4. Chemical reaction catalyst
Magnesium can also be used as a catalyst for chemical reactions, often used in alkylation, hydrogenation, cracking and so on. In these reactions, magnesium catalyst can reduce the reaction temperature, improve the reaction selectivity and yield, which is conducive to the realization of industrial production.
