Carbonaceous materials for the production of aluminium. Calcined coke. Determination of the reactivity to carbon dioxide. Part 1. Loss in mass method

This document specifies a method for determining the reactivity of calcined petroleum coke particles with carbon dioxide by measuring mass loss. It is applicable to carbon materials used in the production of aluminum. The method involves the reaction of the material with carbon dioxide under controlled conditions, followed by the determination of mass loss as an indicator of reactivity. The procedure includes preparation of the sample, conditions for the reaction, and measurement techniques. This part of the standard provides detailed instructions for the mass loss method, ensuring consistency and accuracy in the determination process. It is intended for use by laboratories and industries involved in the characterization of carbon materials for industrial applications.
