Abstract
Provided are a device and a method for preprocessing metallic magnesium. The device includes a chamber, a heating device mounted in the chamber, a gas inlet port mounted on the chamber, and a gas evacuation port mounted on the chamber. The gas inlet port is connected to external inert gas supply equipment for supplying an inert gas into the chamber. The gas evacuation port is connected to an external vacuum evacuation device to evacuate the chamber to vacuum. The heating device functions to heat metallic magnesium having an oxidized surface so as to sublimate a layer of magnesium oxide formed on the surface of the metallic magnesium in a vacuum environment to thereby obtain pure metallic magnesium.
