Anotácia

Description / Abstract: This document specifies a method for the determination of the electrical resistivity of granular carbon (calcined or graphitized) used in the manufacture of carbon electrodes for the production of aluminium. The measurement of electrical resistivity assists in assessing the extent of coke calcination. The electrical resistivity of the coke aggregate will influence the electrical resistivity of the coke electrodes made from it. In general, a more highly calcined coke will have a lower electrical resistivity if other factors, such as grain size, are similar.
