Application Summary AI generated

This standard specifies the method for determining the quinoline-insoluble (QI) content in coal tar pitch used as a binder for carbon anodes in primary aluminium production. It is applied in quality control laboratories and material testing facilities within the aluminium smelting industry to ensure the pitch meets specifications for anode manufacturing. Accurate QI measurement is critical for optimizing anode performance and minimizing impurities during the electrolytic reduction process.
