Abstract
A method of obtaining detonation nanodiamonds from tetryl by means of blasting the latter in a water shell with the explosive/water mass ratio of 1/(10 ÷ 14) is developed. The proposed process ensures the yield of the target product in the amount of 6 ÷ 7 wt. % of the initial mass of the reagent with the content of nanodiamonds in the resultant batch mixture equal to 57 ± 6 %. It is demonstrated that the use of individual explosives offers some advantages over the known multicomponent mixtures in terms of cost efficiency and safety of the charge preparation process.
