HBDD Boron-Doped Diamond Powder
HBDD Series / Grain size 1-2 um and coarser / Specialized
HBDD Boron-Doped Diamond Powder
HBDD Boron-Doped Diamond Powder is a specialized grade from the HBDD series, produced factory-direct at our own base in Zhengzhou, Henan - the Diamond Capital of China. Standard grain size range: 1-2 um and coarser. Each batch is checked for particle size distribution before packing, and can be supplied in trial quantities for process validation.
Advantage
- Boron incorporated into the diamond lattice — a p-type semiconductor, not an abrasive
- Conductivity tunable through the doping level
- Wide electrochemical window with low background current
- Chemically inert and resistant to strong acid and alkali
- Keeps diamond hardness, wear resistance and thermal conductivity
- Supplied from 1 to 2 µm and coarser
Send your workpiece material, target surface finish and order quantity — we confirm the matching grade and sample route within 24 hours.
Product Overview
HBDD Boron-Doped Diamond Powder is a functional diamond material rather than an abrasive. Boron is incorporated into the diamond lattice, which turns an insulator into a p-type semiconductor while keeping the hardness, thermal conductivity and chemical inertness of diamond.
That combination is what makes it useful: an electrode that will not corrode, has a wide electrochemical window and a low background current, and can take a high overpotential for oxidising what other electrode materials will not touch. Doping level controls the conductivity, from semiconducting through to near-metallic at heavy doping.
Typical use is electrode material for hard-to-degrade industrial wastewater treatment, electrochemical sensing of heavy metals and biomarkers, organic electrosynthesis and water electrolysis, and high-temperature or high-power device work. Supply is from 1 to 2 µm and coarser, and doping level and particle size are both set against the application.
Standard Grain Size Chart
Boron-doped diamond is a functional material rather than an abrasive, so the particle size is chosen to suit the way it is used — the boron atoms have to reach the surface for an electrode, and the particle has to disperse for a slurry. Supply starts at 1 – 2 µm and runs coarser.

| 20 – 40 | 20 – 40 | 500 | Bulk electrode material |
Boron doping level is quoted separately from the particle size, because conductivity and particle size are chosen independently. Tell us the application (electrode, sensor, slurry), the target resistivity and the particle size band, and we will confirm both.

Where HBDD Sits In The Functional Diamond Range
Functional diamond is where the diamond stops being only an abrasive. Agglomerates, metal coatings and boron doping each change how the particle behaves in a bond, a slurry or a coating.
| Grade | Type | Base material | Coating / treatment | Typical use |
|---|---|---|---|---|
| HDYS | Agglomerated | Micron diamond plus a special binder | Agglomerated into near-spherical clusters | Wafer thinning and polishing slurries, polishing pads, fine grinding wheels |
| T | Metal coated | Monocrystalline grit | Titanium | Metal-bond stone tools: saw segments, blades and drills |
| N | Metal coated | Monocrystalline grit | Nickel, electroplated or electroless | Resin-bond wheels, electroplated burrs, diamond wire |
| HBDDThis grade | Boron doped | Boron-doped diamond | Electrically conductive, no metal coating | Wastewater treatment electrodes, electrochemical sensing, high-power devices |
