HDN Nano Monocrystalline Diamond Micron Powder
HDN Series / Grain size Nano (confirm) / Monocrystalline




HDN Nano Monocrystalline Diamond Micron Powder
HDN Nano Monocrystalline Diamond Micron Powder is a monocrystalline grade from the HDN series, produced factory-direct at our own base in Zhengzhou, Henan - the Diamond Capital of China. Standard grain size range: Nano (confirm). Each batch is checked for particle size distribution before packing, and can be supplied in trial quantities for process validation.
Advantage
- Nano-scale monocrystalline particles — one crystal, one defined edge
- Holds an edge geometry longer than a polycrystalline particle of the same size
- Disperses into slurries and stays in suspension
- Purity above 99.9 percent
- Ships in 1 to 2 working days from stock
Send your workpiece material, target surface finish and order quantity — we confirm the matching grade and sample route within 24 hours.
Product Overview
HDN Nano Monocrystalline Diamond Micron Powder is a nano-scale monocrystalline grade. The particles keep the single-crystal structure of a monocrystalline abrasive rather than the multi-layer structure of a detonation powder, at a size where they disperse into a slurry and stay there.
Monocrystalline nano diamond holds a defined edge far longer than a polycrystalline particle of the same size, which makes it the grade to reach for when the finishing step has to hold an edge geometry and not just polish.
Typical use is ultra-fine finishing and polishing slurries, and as an additive where a hard, sharp, chemically stable particle is wanted in a fine dispersion. Tell us the target size band and the medium and we will confirm the grade.
Standard Grain Size Chart
Sub-micron diamond powder is the finest end of the same grading ladder and is where most of the surface-quality risk sits: a single oversized particle sets the scratch depth of the whole batch. Every sub-micron lot is classified by settling and checked by laser diffraction before it is released.

Where HDN Sits In The Fine And Nano Range
Below 0.5 µm the specification that decides the result is no longer the average particle size but the top cut and the residue. This table shows the fine and nano grades we produce.
| Grade | Type | Size range | Key property | Typical use |
|---|---|---|---|---|
| HDYM | Monocrystalline, sub-micron | Below 0.5 µm | Uniform PSD, sharp edges | Precision polishing of ceramics, sapphire, carbide and metals |
| HDYMC | Monocrystalline, sub-micron | Custom, sub-0.5 µm | Ash content set to your specification | Slurry and paste formulations with a fixed residue limit |
| HDNThis grade | Nano monocrystalline | Nano range | Monocrystalline nano particles | Ultra-fine finishing and polishing slurries |
| HDPN | Nano polycrystalline | 5 — 500 nm | Detonation synthesis, high specific surface area | Diamond coating, nano polishing, composites, thermal management |
