Development of the Detonation Nanodiamond Synthesis from Tetryl Based Ternary Mixtures

The process of detonation synthesis of nanodiamonds from ternary systems was developed with conversion tetryl as their main component. The dependence of the yield of detonation nanodiamonds and their content in the diamond blend on the tetryl content in the ternary composition was shown as well as that of the yield of detonation nanodiamonds on the oxygen balance of the blend. The conditions and composition of the explosive were found to determine the maximum yield of detonation nanodiamonds, 8.2 wt %, based on which it is possible to develop a more economical and efficient industrial technology for the production of detonation nanodiamonds: the use of explosive compositions containing 50 wt % or more conversion tetryl, respectively, a decrease in the content of expensive and scarce RDX; high content of nanodiamond in the diamond blend, which reduces the cost of chemical cleaning; the possibility of a simple selection of the required oxygen balance of the explosive composition.
