INVESTIGATION OF THE SYNTHESIS OF ULTRADISPERSED DIAMONDS IN MIXTURESOF TNT WITH RDX, HMX, AND PETN

The dependence of the yields of condensed carbon and ultradispersed di amond (UDD), and the fraction of UDD in the carbon, on the composition of cast mixtures of TNT with RDX, HMX, and PETN, are investigated exp erimentally by detonations in a blast chamber. Mixtures having a TNT c ontent from 90 to 35% are studied. It is shown that the yield of conde nsed carbon decreases linearly as the amount of TNT in the mixture is reduced, while the fraction of diamond phase in the carbon increases m onotonically (for mixtures with PETN) or reaches a constant value (for mixtures with RDX and HMX). The dependence of the yield of UDD on com position of the explosive displays an extremum; the maximum yield is a ttained for a TNT content of 60-70%.
