Abstract
L'invention concerne la production électrolytique du fluor. On fait circuler l'électrolyte fondu (KF + HF) d'un réservoir vers une ou plusieurs cellules d'électrolyse (qui sont alors en parallèle) en passant par un échangeur de chaleur permettant de régler la température de l'électrolyte. On prévoit également un moyen pour le dégagement de H2 entraîné par l'électrolyte. Le procedé permet des rendements élevés en fluor pouvant constituer un élément en synthèse minérale ou organique.
