What is Nano Dimaond Powder？
Nano diamond powder is an ultra-fine, high-performance industrial material produced through Detonation Synthesis (DND) or High Pressure High Temperature (HPHT) ball milling methods. In both processes, diamond particles are created or refined at the nanometre scale, delivering exceptional hardness, high surface area, and excellent thermal conductivity. These properties make nano diamond powder ideal for precision polishing, thermal management, surface coatings, and advanced composite materials.
At Crownkyn Diamond, we produce high-purity nano diamond powders using controlled detonation techniques and precision HPHT milling technology. Our product range covers both detonation nano diamond (DND) and HPHT-milled grades, offering stable particle size distribution, surface customisation options, and reliable performance across various industrial applications.
