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.
