Chemical analysis of refractory material glass and glazes - Determination of Fe2+ and Fe3+ by the spectral photometric method with 1,10-phenanthroline (ISO 14719:2011)

ISO 14719:2011 specifies a spectral photometric method with 1,10-phenanthroline for the quantitative determination of Fe2+ and Fe3+ in oxidic raw and basic materials for ceramics, glass and glazes, e.g. feldspar, kaolinites, clay, limestone, quartz refractory materials. ISO 14719:2011 could be extended to other aluminosilicate materials, providing that uncertainty data is produced to support it. However, there might be problems in the decomposition of high-purity alumina and chrome ore samples.
The method is not suitable for reduced materials, such as silicon carbide, graphite-magnesia, etc.

Chemische Analyse von feuerfestem Werkstoff, Glas und Glasuren — Spektralphotometrische Bestimmung von Fe2+ und Fe3+ mit 1,10-Phenanthrolin (ISO 14719:2011)

Diese Internationale Norm legt ein spektralphotometrisches Verfahren mit 1,10-Phenanthrolin zur quantitativen Bestimmung von Fe2 und Fe3 in oxidischen keramischen Roh- und Werkstoffen, Glas und Glasuren, wie z. B. Feldspat, Kaolin, Ton, Kalkstein, feuerfeste Werkstoffe auf Quarzbasis, fest. Diese Internationale Norm könnte auf andere feuerfeste Alumosilicat-Werkstoffe unter der Voraussetzung erweitert werden, dass die Daten zur Einschätzung der Unsicherheit diese Erweiterung zulassen. Proben aus hochreinem Aluminiumdioxid und Chromerzen können jedoch beim Aufschließen Probleme bereiten.
Für reduzierte Werkstoffe, z. B. Siliciumcarbid, Magnesia-Graphit usw., ist das Verfahren nicht geeignet.

Analyse chimique de matériaux réfractaires, du verre et d'émaux - Dosage de Fe2+ et Fe3+ par la méthode spectrophotométrique en utilisant la 1,10-phénanthroline (ISO 14719:2011)

L'ISO 14719:2011 spécifie une méthode spectrophotométrique utilisant la 1,10-phénanthroline pour le dosage quantitatif de Fe2+ et Fe3+ dans des matières premières et des matières de base oxydes pour les céramiques, les verres et les émaux, par exemple les matériaux réfractaires contenant des feldspaths, de la kaolinite, de l'argile, du calcaire, du quartz. L'ISO 14719:2011 pourrait être étendue à d'autres matériaux aluminosilicates, à condition de produire des données d'incertitude pour l'étayer. La décomposition des échantillons d'alumine et de minerai de chrome de haute pureté peut toutefois s'avérer problématique.
Cette méthode ne convient pas aux matériaux réduits tels que le carbure de silicium, le graphite-magnésie, etc.

Kemijske analize ognjevzdržnih materialov, stekla in glazur - Določevanje Fe2+ in Fe3+ s spektrofotometrijsko metodo z 1,10-fenantrolinom (ISO 14719:2011)

Ta mednarodni standard določa spektrofotometrijsko metodo z 1,10-fenantrolinom za količinsko določevanje Fe2+ in Fe3+ v oksidnih surovinah in osnovnih materialih za keramiko, steklo in glazure, npr. v glinencu, kaolinitih, glini, apnencu in kremenovih ognjevzdržnih materialih. Področje uporabe tega mednarodnega standarda se lahko razširi tudi na druge aluminosilikatne materiale, če so ustvarjeni podatki o negotovosti, ki to podpirajo. Vendar lahko pride to težav pri razkrajanju zelo čistih vzorcev boksita ali kromove rude. Metoda ni primerna za reducirane materiale, kot sta silicijev karbid, grafit-magnezij itd.
