Abstract
Process for the preparation of metallic or semimetallic shaped elements, particularly of silicon, in a molten coating bath. Into a confinement crucible is placed the molten basic semimetallic metallic material and a molten coating bath which is inert with respect to said material and whose melting temperature is below that of the material. Into the material is introduced at least one frame-like part, made from a refractory material whose thickness for wetting is greater with respect to the metallic or semimetallic material than with respect to the molten coating bath. A metallic or semimetallic material shaped element is then produced on the frame by the slow displacement of all or part thereof. This shaped element is solidified in the liquid coating bath and finally the complete frame and the solidified shaped element are removed from the bath.
