Nano Diamond Powder for Precision Polishing and Functional Materials
Crownkyn supplies HPHT and detonation nanodiamond for precision polishing, lubricants, coatings and advanced composite formulations. Grades are available with controlled particle or aggregate size, dispersion options and application-specific surface modification.
HND provides controlled nano and sub-micron particle sizes witconsistent abrasive behavior and wear resistance. DND consists of approximately 5 nm primary crystallites and can be supplied in different aggregate or dispersed sizes to match specific processing requirements.
What Is Nano Diamond Powder?
At the nanoscale, diamond has a much higher specific surface area, making surface chemistry and dispersion more important than in conventional micron powders. Nanodiamond can function as both a fine abrasive and a functional additive in lubricants, coatings and composite formulations.
Performance depends on particle or aggregate size, dispersion stability, purity and surface condition. These parameters should be considered together when selecting HND or DND grades.
Nano Diamond Powder Product Types
Choose between HPHT and detonation nanodiamond based on particle structure, dispersion requirements and surface characteristics.
HND – HPHT Nano & Sub-Micron Diamond Powder
Produced from HPHT synthetic diamond through controlled crushing, refinement and classification. HND provides stable nano and sub-micron grades for precision processing and functional material formulations.
Key Performance Points
DND – Detonation Nanodiamond
DND consists of approximately 5 nm primary crystallites with high specific surface area. Aggregate size, dispersion form and surface chemistry can be adjusted for different formulation requirements.
Key Performance Points
Nano Diamond Size, Dispersion & Surface Options
Particle size, product form and surface condition can be matched to different polishing, coating, lubricant and composite systems.
Particle Size Control
HND and DND grades are available with different primary, aggregate or dispersed particle sizes to match the required process.
Powder & Dispersion Options
Nano diamond can be supplied as dry powder or as a customized dispersion for different formulation and processing requirements.
Surface Modification
Surface condition can be adjusted to improve dispersion, carrier compatibility and interfacial bonding in functional formulations.
Final availability depends on the required particle size, carrier system, concentration and surface characteristics.
Nano Diamond Grade Selection
Compare HND and DND by particle structure, size form and formulation requirements to select a suitable nano diamond grade.
| Selection Factor | HND – HPHT Nanodiamond | DND – Detonation Nanodiamond |
|---|---|---|
| Particle Structure | Crystalline nano and sub-micron particles processed from HPHT synthetic diamond | Approx. 5 nm primary crystallites forming aggregate structures |
| Typical Size Form | Controlled nano and sub-micron particle-size grades | Approx. 5 nm crystallites with controlled aggregate sizes |
| Performance Focus | Stable abrasive, wear and particle-size performance | High surface area, dispersion control and surface functionality |
| Key Selection Focus | Particle size distribution, purity and batch consistency | Agglomeration, dispersion, surface chemistry and purity |
Selection note: The smallest nominal size is not always the best choice. Final performance also depends on dispersion stability and compatibility with the application system.
