Produits carbonés utilisés pour la production de l'aluminium — Coke calciné — Détermination de la taille de la cristallite du coke calciné de pétrole par diffraction aux rayons X

ISO 20203:2005 describes a test method for the determination of the mean crystallite height of a representative, pulverized sample of calcined petroleum coke by interpretation of an X-ray diffraction pattern produced through conventional X-ray scanning techniques.

ISO 20203:2005 applies to carbonaceous materials used in the production of aluminium.
