Abstract

The physical nature of the experimentally found anomalous type of the concentration dependence of thermal conductivity of binary ceramic composites is interpreted. A model of the structure and procedure of calculating (predicting) the thermal conductivity of composites of the group of “eutectic models” is proposed.
