Краткое описание

Experimental data are obtained showing that different additions and modificators linked with the surface of nanodiamonds played an important role in the compaction at a high pressure. Methods of modification of the nanodiamond surface before the compaction of nanodiamonds at a high pressure have been developed, and as a result, composite powders such as nanodiamond − X (where X is B, Si, Ti, Co, and nanographite) have been obtained. It is shown that modification sometimes leads to a decrease in the regimes of sintering and influences the recrystallization and graphitization of nanodiamond grains in high-pressure treatment. As a result, it was possible to produce materials with the required nanostructure that determines the properties of compacts based on nanodiamonds.
