Results are given for a study of the dependence of apparent density and ultimate strength in compression on the quantity of silica and form of modifying addition (Al, Si, B and mixtures of them) for materials of the composition Al2O3-SiC-C based on high-alumina cement and aluminochromium phosphate binder after low-temperature (400°C) heat treatment. It is established that the most efficient form the point of view of compaction and strengthening of raw material of corundum-graphite refractory is addition of aluminum powder. © 2010 Springer Science+Business Media, Inc.
