Product Description

Detonation Nanodiamond (DND) powder is produced by the detonation of oxygen-deficient explosive mixtures (such as TNT/RDX). Under extremely high temperature and pressure, carbon is transformed into diamond nanoparticles. After purification and surface treatment, the powder delivers outstanding hardness, thermal conductivity, and surface activity.

Key Features

• Large Specific Surface Area：Small granularity of the product, specific surface area up to 300- 420m2/g.

• Good Dispersibility：Small particle size, in the dispersion medium, can maintain good dispersion and suspension, not easy to precipitate.

• High Processing Precision：Excellent ultra-fine polishing effect, can make the surface roughness of the workpiece reach below 0.2nm.

• Stable surface chemistry: contains various functional groups (–OH, –COOH, –C=O), enabling strong bonding with metals, ceramics, polymers, and coatings.
