OFTech Nano-diamond is made from the detonation of high power explosives under minus balance of oxygen. The detonation brings out a proper diamond-growing condition with high temperature, super high pressure and isolated carbon atoms. Nanodiamond is different from normal synthetic diamond. It is round without any edges and corners and its crystal size is about 3-15nm.
