The thermophysical and thermomechanical properties of a number of heat-insulating materials (thermal conductivity, apparent density, deformation temperature under load, permanent change in size on heating, com-pressive strength, thermal linear expansion) used, in particular, for the bottom refractory lining in aluminum electrolyzers, are examined. Factors capable of affecting these properties are considered. The behavior of heat-insulating materials under service conditions of a thermal power unit is considered.
