BS 6043 discusses carbonaceous materials used in aluminium manufacture. BS 6043-4.9 belongs to the BS 6043 multi-series and discusses the determination of ash.
BS 6043-4.9 specifies a method for the determination of ash in the pitch for electrodes used in the production of aluminium.
The method is applicable to products (tar pitch, petroleum pitch, etc.) producing a quantity of ash greater than or equal to 0,05 % (m/m).
Note: If it is required to express the result on the dry product, carry out the water determination by azeotropic distillation as specified in ISO 5939. Refer to the result of the determination of ash obtained on the product as such, to the dry product.
BS 6043-1.8 on the determination of ash in the pitch for electrodes used in the production of aluminium is useful for:
Ash contributes to the strength, density, and electrical conductivity characteristics of the anode (and cathode) necessary for the efficient conversion of powder alumina to liquid aluminium. BS 6043-1.8 provides you with a method to determine ash in the pitch for electrodes used in the production of aluminium.
BS 6043-1.8 guides you with the materials, apparatus and sampling required for the test procedure. BS 6043-1.8 guides you with the test procedure and calculation of results. BS 6043-1.8 helps you manufacture high-quality aluminium.
