Some physical and technological features of the electroconsolidation process were considered to determine its place among numerous electrodischarge sintering methods. Principal advantages over the other nanopowder compaction methods were noted. The effect of sintering regimes on the formation of a microstructure, the specific features of inhibition under heating in the growth of grains, and the temperature of the graphite press mold and the rate of its heating on the physicomechanical properties of ceramic composites was studied. Some original data on the electroconsolidation process were reposted alongside with the physicochemical properties of nanocomposites synthesized by this method. The probable scheme of electrodischarge processes under high-ampere currents through the graphite press mold is presented.
