Stabilization and holding of metals by magnetic field
Abstract
Most metals in a molten state have a high degree of chemical activity. The material of the crucible dissolves in the molten metal and contaminates it. Modern technology has often posed the problem of obtaining a metal which is of the same purity after melting as before. This problem becomes particularly acute when superpure and refractory materials are desired. A promising solution to this problem appears to be the use of an electromagnetic crucible. A device is described in which molten metal is held by the forces of the electromagnetic field and does not have direct contact with any substance.
