Advanced technical ceramics - Methods of test for ceramic powders - Part 2: Determination of impurities in barium titanate

This part of EN 725 describes a method for the determination of impurities in barium titanate powders using inductively coupled plasma optical emission spectroscopy (ICP-OES).
The method is applicable only to stoichiometric barium titanate. The maximum concentrations measured for each impurity are as follows:
   Sr   4 mg/g (4 000 ppm)
   Ca   500 ug/g (500 ppm)
   K   200 ug/g (200 ppm)
   Na, Mg, Al, Fe, Nb   100 g/g (100 ppm)
The minimum concentration or detection limits are from 1 ug/g to 5 ug/g (1 ppm to 5 ppm).

Céramiques techniques avancées - Méthodes d'essai pour poudres céramiques - Partie 2 : Détermination des impuretés dans le titanate de baryum

La présente partie de l’EN 725 décrit une méthode permettant la détermination des impuretés présentes dans les poudres de titanate de baryum par spectrométrie d’émission avec plasma à couplage induit par haute fréquence et détecteur optique (ICP-OES).
La méthode ne s’applique qu’au titanate de baryum st chiométrique. Les concentrations maximales mesurées pour chaque impureté sont les suivantes :
   Sr   4 mg/g (4 000 ppm)
   Ca   500 µg/g (500 ppm)
   K   200 µg/g (200 ppm)
   Na, Mg, Al, Fe, Nb   100 µg/g (100 ppm)
Les limites de concentration minimale ou de détection s’échelonnent entre 1 µg/g et 5 µg/g (1 ppm et 5 ppm).
