Abstract
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.
