BDD – Boron Doped Diamond Powder

20+ Years Experience Consistent Batch Quality Customized Solutions

Product Overview

BDD is a boron-doped synthetic diamond material produced through HPHT synthesis, combining diamond hardness and chemical stability with controlled semiconductive to conductive properties. Available in mesh/grit and micron grades, it is suitable for electrochemical materials, conductive abrasive tools and other functional applications requiring electrical activity together with diamond durability.

Features

Boron-Doped Diamond Structure: Boron incorporated into the diamond lattice introduces controlled electrical functionality while retaining the mechanical properties of synthetic diamond.
Semiconductive to Conductive Behavior: Electrical performance can vary according to boron concentration, particle characteristics and final material or electrode structure.
High Chemical Stability: Diamond structure provides strong resistance to chemical attack in demanding functional and electrochemical environments.
Electrochemical Functionality: Suitable for BDD-based electrode and electrochemical systems requiring stable operation and a broad working potential range.
High Hardness and Wear Resistance: Maintains diamond’s mechanical durability for abrasive and specialized grinding applications.
Mesh and Micron Grades Available: Particle size can be selected according to abrasive, electrode and functional material requirements.

Boron-Doped Diamond (BDD) Electrodes

Boron-Doped Diamond (BDD) electrodes achieve semiconductive to quasi-metallic conductivity through controlled boron doping, making them highly effective for demanding electrochemical processes. They provide an exceptionally wide potential window, very low background current, and strong electrochemical stability for reliable, repeatable performance.

BDD electrodes also offer excellent thermal, dimensional, and chemical stability in both aqueous and non-aqueous electrolytes, with high resistance to chemical and electrochemical corrosion. As a result, they are widely used in electrochemical oxidation for wastewater treatment, as well as in electrochemical analysis, synthesis, bioelectrochemical systems, and other industrial electrochemical applications.
