Dosage de l'oxyde de bore(III) dans les produits réfractaires — Partie 2: Méthode d'extraction acide pour le dosage de l'oxyde de bore(III) dans les composants de liant

Abstract / scope

ISO 21078-2:2006 specifies procedures of chemical analysis for the determination of boron(III) oxide used as a binder component added to aluminosilicate refractories, using an acid extraction method.

It is applicable for refractories containing less than 1 % (mass fraction) of boron(III) oxide.
