DND-Detonation NanoDiamond

20+ Years Experience Consistent Batch Quality Customized Solutions
Product Overview
DND is an ultra-fine nanodiamond produced by controlled detonation synthesis, with primary diamond crystallites typically around 4–5 nm. Its extremely small primary size, high specific surface area and tunable surface chemistry make it suitable for ultra-fine polishing, surface modification, tribological formulations and functional nanocomposites where nanoscale interfacial interaction is important.

Features

  • Ultra-Fine Primary Nanocrystals: Primary diamond crystallites are typically around 4–5 nm in size.
  • Very High Specific Surface Area: Nanoscale dimensions provide extensive surface area for interfacial and functional applications.
  • Rich Surface Chemistry: Purification and oxidation can introduce oxygen-containing surface groups that enable further surface modification.
  • Deagglomeration & Dispersion Control: Processing can reduce strongly bound aggregates and improve dispersion in selected liquid and composite systems.
  • High Nanoscale Hardness: Provides fine abrasive action for ultra-fine polishing and surface treatment.
  • Surface Functionalisation Capability: Surface chemistry can be modified according to dispersion, composite and specialty functional requirements.

*For DND, reported particle size depends strongly on whether primary crystallite size, aggregate size or hydrodynamic size is measured. Particle-size specifications should therefore be confirmed together with the measurement method and dispersion condition.
