Abstract

Seams of traditional insulating and refractory materials, reduce gas-density of a laying and are places of receipt of aggressive liquid and gaseous components in heat-insulating part of cells cathodes. It causes growth of thermal losses and reduces cells service life. Unshaped material materials which are in a disperse state are considerably deprived of such shortcomings. High efficiency at their production and application caused expansion of scales of their application. However need of careful selection of particle size distribution and strong consolidation of dry barrier mixes, possibility of their division according to fractions in the course of installation increases their cost and imposes certain restrictions on their use. In work results of laboratory, theoretical and industrial researches new unshaped materials with use of products of pyrolysis of coals of the Kansk and Achinsk pool which advantage in relation to the traditional unshaped materials is good physical and working properties and low cost are presented
