The use of magnesium in electronics
This is a very lightweight fusible metal, its density is about 1.7 g/cm3 at 20 °C, and melting point = equal to 650 °C. its Surface is covered with the oxide film, which is destroyed at 623 °C, after which Mg is burned. Powders of potassium permanganate and magnesium are explosive.
|Atomic (molar) mass, g/mol||24,3|
|The melting temperature t°C||650°C|
|The heat of fusion kJ/mol||9,2|
|The thermal conductivity K [W/(m·K)]||158|
|Heat of evaporation kJ/mol||131,8|
This is one of the most high-tech metals. But as a structural material more valuable alloys thereof. With a large number of metals, magnesium is capable of forming corrosion-resistant materials with high specific strength.

In the electronic industry, instrument making, a magnesium rolled parts are produced devices, body cameras, mobile phones, binoculars, portable cameras. Magnesium alloys are also used for the production of electric batteries and a small percentage of absorption of thermal neutrons and the absence of interactions with uranium was the cause of the production of the magnesium shells of fuel elements of nuclear boilers.
