Abstract
Semi-graphite, very often used in some other industries, was tested 25 years ago as a cathodic material for the aluminum cell. To-day, since energy costs have increased, semi-graphite becomes again a good solution for the cell lining. In this text, we have described its production process and its characteristics are given according to the temperature. Compared to pure graphite, it has got better mechanical characteristics (the same as standard carbon), a lower thermal conductivity, roughly the same resistivity and a lower cost. Computer studies and trials show that the use of semi-graphite leads to a good cell productivity, a low energy consumption and a long potlife.
