ActiveCarbonaceous materials used in the production of aluminium―Pitch for electrodes―Part 9：Determination of sulful content by the bomb method
原铝生产用炭素材料 煤沥青 第9部分：氧弹燃烧法测定硫含量
Application Summary AI generated
This standard specifies the bomb method for determining sulfur content in coal tar pitch used as a binder in carbon electrodes for primary aluminum smelting. It is applied in quality control laboratories of aluminum smelters and electrode manufacturers to ensure pitch meets sulfur limits that affect anode performance and environmental emissions. The method involves combusting a pitch sample in a pressurized oxygen bomb and analyzing the resulting solution for sulfate content.
