Abstract
Heat-insulating materials for the lining of aluminum electrolysis cells based on diatomite, vermiculite, perlite, and calcium silicate are briefly reviewed. Data on heat conductivity of these materials over the range of 200 – 800°C are given, with emphasis placed on the behavior in the electrolysis bath. Properties of heat-insulating materials available from domestic and foreign manufacturers are discussed in terms of the classification temperature and safe operating temperature.
