    摘要： 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.

    摘要： The invention relates to a process for producing plates of a metallic or semimetallic material.The latter is in the form of a liquid mass entirely separated from the walls of a crucible by a liquid film of a second material. A group of plates is lowered into the crucible, in order that the liquid mass can solidify, while being separated from the plates by the protective liquid film.Application is to the production of photovoltaic silicon plates.
