molybdenum processing | Britannica

In one such process, developed by Parke and Ham, molybdenum powder is continuously pressed into a rod, which is partially sintered by electric resistance and melted at the end in an electric arc. The molten molybdenum is deoxidized by carbon added to the powder, and it is cast in a water-cooled, copper mold.
