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.

Overview

ISO 20203:2005 is an international standard developed by the International Organization for Standardization (ISO). It specifies a test method for determining the mean crystallite height of calcined petroleum coke using X-ray diffraction (XRD) techniques. This method focuses on pulverized samples of calcined petroleum coke, which is a key carbonaceous material used in the production of aluminium. The crystallite height determined by this procedure serves as an indicator of the heat treatment extent during calcination, thereby influencing the suitability of coke for end-use applications in aluminium manufacturing.

Key Topics

Calcined Petroleum Coke Characterization

Standardized method for measuring mean crystallite height (Lc)
Application of conventional X-ray scanning to analyze coke samples

X-Ray Diffraction Technique

Usage of a powder diffractometer with Cu-Kα radiation
Methods for sample preparation (e.g., back-fill, front-fill, side-loading, and briquetting)
Calibration using reference materials such as silicon or quartz

Measurement and Calculation

Interpretation of X-ray diffraction patterns, focusing on the (002) lattice plane of graphite
Determination of full-width half maximum (FWHM) for calculation
Use of the Scherrer equation to derive the mean crystallite height

Analysis Precision

Definitions and guidelines on repeatability and reproducibility to ensure data consistency

Applications

The application of ISO 20203:2005 is vital in several areas within the aluminium production chain and related industries:

Quality Control in Aluminium Production

Ensures that calcined petroleum coke meets specific structural requirements for use as anode and cathode materials in aluminium electrolysis cells
Helps producers maintain consistent product quality, improving process efficiency and product yield

Material Research and Development
