PROCESS FOR PRODUCING HEAT-ACCUMULATOR CERAMIC BLOCKS FROM RED CLAYS OF THE BAYER PROCESS

摘要

Process for producing heat-accumulator ceramic blocks from red clays of the Bayer process, by chamotting and granulation of said clays and subsequent conformation of the blocks and kilning at high temperature. It provides for the production of dense blocks which have a high mechanical resistance and are chemically inert, and of which the calorific capacity makes them appropriate to be used as heat accumulators, particularly in night rate electric accumulators. The main advantages of said process are that highly contaminating residues (red clays of the Bayer Process) can be reused to produce accumulators having thermal characteristics similar to those of products available in the market.
