The basic reaction, is endothermic—that is, heat must be applied to initiate and sustain it. With magnesium reaching a vapour pressure of 100 kilopascals (1 atmosphere) at 1,800 °C (3,270 °F), heat requirements can be quite high. In order to lower reaction temperatures, industrial processes operate under vacuum.

What is Magnesium? Magnesium is the lightest of all commonly used structural materials with a density of 1.7g/cm 3 (106.13lb/ft 3) approximately 1/3 lighter than aluminum. It is the 8th most abundant element in the earth’s crust however, it is rarely found in its pure form due to the fact that it bonds with other elements easily.
