Abstract
Dispositif pour fabriquer en continu, par la méthode de la goutte pendante, des monocristaux préformés en forme de plaques comportant un creuset destiné à recevoir la matière servant à fabriquer le monocristal et percé d'un orifice capillaire caractérise par le fait que les lèvres inférieures dudit orifice capillaire ne sont pas au même niveau horizontal. Le dispositif de l'invention permet un bon contrôle et une bonne regulation de la matière alimentée et rend aisé le contrôle de la qualité du liquide. Les plaques monocristallines trouvent des applications notamment en bijouterie, en horlogerie et en électronique.
