Advanced technical ceramics - Methods of test for ceramic powders - Part 12: Chemical analysis of zirconia

This part of EN 725 specifies methods for the determination of the levels of silicon, aluminium, titanium, iron, calcium, magnesium, potassium, sodium, yttrium, hafnium, cerium and strontium using flame atomic absorption spectrometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP - AES).  These methods are applicable to the concentration ranges given in clause 3, expressed as oxides.

Hochleistungskeramik - Prüfverfahren für keramische Pulver - Teil 12: Chemische Analyse von Zirconiumoxid

1 Anwendungsbereich
Dieser Teil von EN 725 legt Verfahren für die Bestimmung der Gehalte von Silicium, Aluminium, Titan, Eisen, Calcium, Magnesium, Kalium, Natrium, Yttrium, Hafnium, Cerium und Strontium mit Hilfe der Flammen-Atom-absorptionsspektrometrie (FAAS) und der Atomemissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-AES) fest. Diese Verfahren sind auf die in Abschnitt 3 angegebenen Konzentrationsbereiche der oxidischen Verunreinigun-gen anwendbar.

Céramiques techniques avancées - Méthodes d'essai pour poudres céramiques - Partie 12: Analyse chimique de la zircone

La présente partie de l'EN 725 spécifie des méthodes permettant le dosage de silicium, d'aluminium, de titane, de fer, de calcium, de magnésium, de potassium, de sodium, d'yttrium, d'hafnium, de cérium et de strontium, par spectrométrie d'absorption atomique dans la flamme (FAAS) ou par spectrométrie d'émission atomique avec plasma à couplage inductif (ICP - AES). Ces méthodes s'appliquent aux gammes de concentration indiquées dans l'article 3, exprimées sous forme d'oxydes.
