ActiveCarbonaceous materials for the production of primary aluminium - Pitch for electrodes - Part 5：Determination of content of toluene-insoluble material
原铝生产用炭素材料 煤沥青 第5部分：甲苯不溶物含量的测定
Application Summary AI generated
This standard specifies a test method for determining the toluene-insoluble content in coal tar pitch used as a binder for carbon electrodes in primary aluminium production. It is applied by aluminium smelters and pitch manufacturers to control the quality and performance of electrode pitch, as the toluene-insoluble fraction directly influences the coking behavior and mechanical strength of the baked anodes. The method is essential for ensuring consistent anode quality in the Hall-Héroult electrolytic process.
