Title (EN) DEVICE FOR MEASURING THE CONCENTRATION OF FLUORINE IONS OR A METALLIC FLUORIDE RATIO IN A MELT OR GAS MIXTURE
(FR) DISPOSITIF PERMETTANT DE MESURER LA CONCENTRATION EN IONS FLUOR OU UN RAPPORT DE FLUORURES DE METAL DANS UNE MATIERE EN FUSION OU UN MELANGE GAZEUX
(DE) VORRICHTUNG ZUR MESSUNG DER KONZENTRATION VON FLUORIONEN BZW. EINES VERHÄLTNISSES VON METALLFLUORIDEN IN EINER SCHMELZE ODER EINEM GASGEMISCH
Abstract:
(EN) In order to be able to measure the concentration of fluorine ions or a metallic fluoride ratio in a melt (18) or gas mixture, the invention proposes a device which comprises a solid electrolyte (1) of calcium fluoride, a reference electrode (2) made of a metal and the corresponding metallic fluoride, and a voltage-measuring device (3) which can be connected both to the reference electrode (2) and to the melt (18) or gas mixture acting as the working electrode via a diverter (4 and 5).
(FR) Pour mesurer la concentration en ions fluor ou un rapport de fluorures de métal dans une matière en fusion (18) ou un mélange gazeux, il est prévu un dispositif comprenant un électrolyte solide (1) en fluorure de calcium, une électrode de référence (2) réalisée dans un métal et dans le fluorure de métal correspondant et un dispositif de mesure de la tension (3) pouvant être relié aussi bien à l'électrode de référence (2) qu'à la matière en fusion (18) ou au mélange gazeux servant d'électrode de travail, par l'intermédiaire d'une dérivation (4 et 5).
(DE) Um die Konzentration von Fluorionen bzw. ein Verhältnis von Metallfluoriden in einer Schmelze (18) oder einem Gasgemisch messen zu können, wird eine Vorrichtung vorgeschlagen, die aus einem Feststoffelektrolyten (1) aus Calciumfluorid, einer Referenzelektrode (2), die aus einem Metall und dem betreffenden Metallfluorid besteht, und einer Spannungsmeßeinrichtung (3) besteht, die über je einen Ableiter (4 und 5) sowohl mit der Referenzelektrode (2) als auch mit der oder dem als Arbeitselektrode dienenden Schmelze (18) bzw. Gasgemisch verbindbar ist.
