Detonation nanodiamonds


So nanodiamonds is widely known to form after detonations,

This may be a already tested or asked already, but what if we had a charge that have carbon in the center, does a bigger diamonds (visible size) form from the converging shockwave?

After hearing about the nanodiamonds, I thought the same thing, although I first imagined it would work with a "spherical implosion" type setup, with the control electronics housed far enough away to be protected in a steel box and reused. But realistically, I don't think you would get a single crystal, and diamonds are vulnerable to both heat and especially shock.

But a kilogram artificial diamond would be pretty cool.

Diamonds are crystalline carbon, and forming crystals takes time. The bigger the crystals, the longer it takes.

Yes sir, this is an implosion device loosely adapted from Fat Man

they are just diamond grains with nanometer size .
and it didn’t made by implosion it made by explosion/quenching , which mean that the explosive charge exploded inside a cold water or even liquid nitrogen !!
carbon powder is not necessary as any oxygen-deficient explosive like TNT will work.

right, but I was envisioning a whole crystal forming in the center from the detonation, but as others pointed out, any formed diamond may still be nano sized since they take time to grow.

I feel ignorant. I thought large diamonds could be made like the “fat boy” wave shaping set up.... didn’t think it would take time for crystals to grow. But your tight it’s true for every other material.
