DEVICE AND METHOD FOR PREPROCESSING METALLIC MAGNESIUM

摘要

The present invention provides a device and a method for preprocessing metallic magnesium. The device includes a chamber (20), a heating device (22) mounted in the chamber (20), a gas inlet port (24) mounted on the chamber (20), and a gas evacuation port (26) mounted on the chamber (20). The gas inlet port (24) is connected to and in communication with an external inert gas supply equipment for supplying an inert gas into the chamber (20). The gas evacuation port (26) is connected to and in communication with an external vacuum evacuation device to evacuate the chamber (20) to vacuum. The heating device (22) 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. The present invention can remove magnesium oxide from surfaces of particles of metallic magnesium, reduce the content of magnesium oxide, allowing it possible to handle an extremely minor amount of magnesium oxide in a coating chamber so as to prevent the coating chamber from being contaminated by a large amount of magnesium oxide and thus greatly reduce the chance of defect products resulting from magnesium oxide.
