Abstract
A number of quality conditions must be met in a good Søderberg binder, both with respect to cell operation and potroom working environment. Among the more important are low evaporation loss of pitch, acceptable rheological properties which are maintained over a wide range of temperatures, and good enough quality of the binder coke to avoid problems in the baking and consumption zones.
