  • Features of Synthetic Nano Diamond Powder

  • 1. The shape of diamond nano powder particles is nearly spherical; With good wear resistance and hardness ;

    2. With high specific surface area and porous structure ;

    3. High thermal stability, excellent thermal conductivity ;

    4. With unique corrosion resistance ;

    5. Ultra-high purity, the total amount of various metal impurities is stable at ppm level. Purification and surface modification for different needs make the surface functional groups controllable ;

    6. Unique surface modification makes it have good stability and dispersibility in water-based, oil-based and other conditions ;

    7. Mature and stable grading technology makes our products suitable for various applications with strict requirements for particle size distribution ;

    8. All series of products are suitable for different industries .


Sgni nano diamond is formed with tiny crystals that are no more than 20nm. Special detonative synthetic condition produces sphere shaped diamond with rich functional group on the surface. Its specific surface area is lifted an order of magnitude contrasted with monocrystalline diamond. It possesses characteristics of both diamond and nano functional materials.

Depending on requirements of different applications, nano diamond primary products should pass procedure of purification, surface modification and precise grading treatment, which are our exclusive technology. Different post-processing can provide all series of nano diamond products with full specifications and types.


Basic particles are sphere shape diamond crystals with size 5-20nm.
High hardness & wearing resistance of diamond.
High specific surface area, porous structure.
High heat stability, excellent thermal conduction.
Peculiar anti-causticity.
Special surface modification treatment makes stable dispersing in both water & oil medium.
Mature stable grading technics make our products suitable for all fields requiring strict PSD.
Superhigh purity, main metal impurity below ppm, purification and surface modification treatment for different needs make surface functional group controllable.

Remarks: Special requirements can be tailor-made.

Application field:

1. Super fine polishing. The surface roughness of polished workpieces could reach angstrom-level without scratches, which can satisfy the most rigorous polishing applications demand.

2. Lubricating and antifriction. Nano diamond can be used as lubricating oil additives. The sliding friction will be changed into rolling friction. Which can reduce the friction coefficient and significantly improve the friction performance and also prolong the service life.

3. Composite plating and spraying on the surface of various workpieces. Nano diamond can enhance wear resistance, corrosion resistance, impact toughness and hardness of the workpieces’ surface.

4.As rubber and plastics additives, nano diamond can significantly enhance its wear resistance, puncture resistance, tensile property and also slow down the ageing process.

5. High purity nano diamond will not cause biological rejection, meanwhile it can be widely used in medical, biological and cosmetic fields because of its big specific surface area, strong adsorption potential.
