ASTM D5187

Crystallite Size (Lc) of Calcined Petroleum Coke by X-Ray Diffraction

Applicability: ASTM D5187 applies to the determination of the crystallite size in calcined petroleum coke using X-ray diffraction. It is used to evaluate the quality of calcined petroleum coke by measuring the average thickness of its crystallites, which is critical for applications like the manufacturing of aluminum, steel, and electrodes.

Purpose: The purpose of ASTM 5187 is to determine the average thickness of the crystallites in a pulverized sample of calcined petroleum coke.
