ABSTRACT:
A semiconductive crucible is provided for use in an electric arc furnace. The semiconductive crucible diverts and diffuses the protons around the anode before completing the electric circuit to form an arc, and thereby reduces the risk of a wayward arc reaching and scarring the wall of the mold.
