摘要
For detonation nanodiamonds of various manufacturers the author has assessed the degree of cohesion of nanodiamond particles, which has an influence on their quality and depends on the synthesis conditions. Depending on the synthesis scaling factor the degree of cohesion increases in the following series: individual particles-porous polycrystals-nonporous abrasive polycrystals. The graphitization kinetics and temperature have been calculated as functions of the nanodiamond particle size and degree of cohesion.
