Описание: Carbon-containing explosive with negative oxygen balance is placed in a shell of condensed phase including reduction agent.Mass ratio of reduction agent to carbon-containing explosive is not less than 0.01:1. Detonation is performed in closed volume in gas medium inert to carbon.

Detonation product is processed by 2-40% aqueous nitric acid together with oxygen of compressed air at 200-280°C

and pressure of 5-15 MPa. Obtained nanodiamond includes carbon of cubic diamond modification and roentgen-amorphous phase at the

ratio of (82-95):(18-5) wt % respectively. Element composition of nanodiamond, wt %: carbon 90.2-98.0; hydrogen 0.1-5.0; nitrogen 1.5-3.0; oxygen 0.1-4.5.

EFFECT: improved process safety, obtaining nanodiamond with predictable properties at industrial scale. 3 cl, 5 tbl
