Features are studied for sintering materials prepared by semidry compaction using potassium polytitanate as a precursor powder, modified with cobalt compounds and given preliminary heat treatment at 700°C. Phase composition, thermomechanical and electrophysical properties of ceramic specimens synthesized at 700, 950, and 1100°C are studied. The mechanism of processes occurring during sintering the ceramic studied at different temperatures and its effect of ceramic properties is studied. It is shown that at 700°C optimum properties are exhibited by ceramic specimens sintered below 750°C. The possibility is considered of using ceramic of this type within the composition of thermoelectric and thermoelectrochemical units intended for energy accumulation from dissipated heat of metallurgical production furnace equipment.
