To determine the dependence of the yield of detonation nanodiamonds (DNDs) on the power of explosives used, a new concept is introduced—the specific power of explosives (to which the detonation velocity of explosives and the pressure of gases in the Chapman-Jouguet plane are related), which is given by the ratio of the heat of explosion to the unit mass and time. The DNDs yield has been found to depend on the detonation velocity and pressure in the Chapman-Jouguet plane. The optimum yield of DNDs (> 5 wt %) is achieved when the specific power of explosives is 30000 to 60000 kJ/(kg·µs), the detonation velocity is 7250 to 8000 m/s, and the pressure in the Chapman-Jouguet plane is 21 to 28 GPa.

爆轰纳米金刚石产率对爆轰过程参数的依赖性

为了确定爆轰纳米金刚石（DND）的产量对所使用炸药功率的依赖性，引入了一个新概念-炸药的比功率（炸药的爆炸速度和Chapman-Jouguet平面中气体的压力）是相关的），它是由爆炸热与单位质量和时间之比得出的。已经发现，DND的产率取决于查普曼-乔格平面中的爆轰速度和爆破压力。当炸药的比功率为30000至60000 kJ /（kg·µs），爆炸速度为7250至8000 m / s，并且在Chapman-Jouguet中施加压力时，可实现DND的最佳收率（> 5 wt％）平面为21至28 GPa。
