ActiveCarbonaceous materials for the production of primary aluminium - Pitch for electrodes - Part 3：Determination of density - Pyknometric method
原铝生产用炭素材料 煤沥青 第3部分：密度的测定 比重瓶法
Application Summary AI generated
This standard specifies the pyknometric method for determining the density of coal-tar pitch used as a binder in carbon electrodes for primary aluminium production. It is applied in quality control laboratories within the aluminium smelting and carbon electrode manufacturing industries to ensure consistent pitch density for optimal electrode performance. The method is critical for verifying raw material specifications during procurement and production of anodes for electrolytic reduction cells.
