Nano-diamonds: Nano-diamonds are produced by using free carbons generated in the detonating process of negative oxygen balance explosives, and controlling detonation pressure and temperature to transfer them into microcrystalline diamond particles with diameters of 5-20 nm. The special synthetic condition makes the shape of their basic particles into near sphere. Their surfaces have rich functional groups, specific surface area increased by an order of magnitude compared to ordinary diamond products. The Nano-diamonds not only have better hardness and abrasive characteristics than ordinary man-made diamonds, but also have new features of nano-function materials.

By product category, Nano-diamonds can be divided into two series:

1Black powder
2Nano-diamond
 

Nano-diamond applications:

}  Ultra-fine polishing, characteristics of particles determines that almost no scratches will be made, can meet polishing applications demanding very high smooth finishing.
}  Reducing lubricated friction, used in lubricant additives to transfer sliding friction into rolling friction, thus lower coefficient of friction can be obtained, and significantly improve lubrication performance and prolong use life.
}  Composite plating and coating spraying on the surface of various workpieces, can improve wear resistance, corrosion resistance, impact toughness and hardness of the surface of workpiece.
}  Used as rubber and plastic additives, significantly enhance its wear resistance, puncture resistance and tensile resistance, slowing the aging process.
}  Nano-diamond almost would not cause biological rejection, and has good applications in medical, biological and cosmetic fields due to its large specific surface area, strong adsorption and adhesiveness characteristics.
