Carbonaceous materials used in the production of aluminium. Calcined coke. Determination of crystallite size of calcined petroleum coke by X-ray diffraction Ingestion-build-134498 The specifications cover structures travelling1 Scope This International Standard 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. It applies to carbonaceous materials used in the production of aluminium. Calcined petroleum coke contains crystallites of different heights. This test method covers the
