Method and apparatus for casting conductive and semiconductive materials

Patent ·
OSTI ID:5907149

An apparatus is described for use in a process for casting a conductive or semiconductive material, comprising: conductive members arranged to be spaced from one another so as to define a container-like area for receiving and containing the material; and means for inducing first electrical currents in each of the conductive members, which first electrical currents act collectively to induce a second electrical current in the material. The second electrical current flows in a direction substantially opposite to the common direction of flow of the first electrical currents, so that the material is repelled away from an substantially prevented from contacting the conductive members during the casting of the material.
