ABSTRACT:
A molten region is formed in a solid material disposed on a cooled hearth capable of rotation. The solid material acts as a crucible for the melt, and single crystals or textured polycrystals may be grown from the molten region, with simultaneous rotation of the hearth and contained solid. The melt is formed in the solid material by one or more electric arcs struck between the material which may behave as an anode, and one or more cathodes which are directed toward the material, so that the electron and plasma flow from the cathodes to the material, produces and maintains the melt.
