In 1963, Soviet researchers discovered that the nano-diamond, also called Ultra Dispersed Diamonds or UDDs, could be created by nuclear explosions caused carbon-based explosives. Since then, detonation has been used as a method of preparing this promising material.

Synthesis Nano-Diamond Powder by Detonation Method:

The detonation technique is more energy efficient and has a higher reaction rate than the other methods. Nano-diamonds are now the result. One of the major industrial production methods.
The detonation method has a high production efficiency for nano-diamond. The idea is to convert carbon from the explosion system by using high temperatures and pressures generated in the explosion. A nano-diamond-containing black powder, which is thermodynamically stable, is prepared by this method. The black powder undergoes a special treatment to produce gray nano-diamond dust. The recovery rate is approximately 8-10%, the diamond particle sizes are 5-10nm and the purity after chemical purification is 95-97%.

Application nanodiamond Powder:

Nanodiamonds have unique properties that make them useful in many fields, including precision polishing and lubrication.
Nano-diamond pastes and suspensions for polishing materials are used by semiconductor silicon wafers. Magnetic computer heads, radios and televisions, machine manufacturing, gemstones, medicine and other industries. The advantage of this product is that the surface roughness Ra value can be as low as 2-8nm and it can create a mirror finish on any solid.
By adding nano-diamonds powder to the lubricating fluid, the friction is transformed from sliding to rolling. The friction pairs are gradually modified, resulting in hard and smooth metal carburized surfaces. Its antifriction, antiwear, and fuel-saving effects are unmatched by other organic chemical methods.
It is a combination of nanoparticles as well as super-hard materials. This powder can be used to create reinforced resin and rubber. This application has a major impact on the material's thermal conduction, polymer degradation temperatures, strength, and resistance to wear. The development of nano-diamonds in new composites is therefore very promising. The nano-diamond sheet has excellent optical properties. It not only offers high light transmittance and a high refractive indices, but it also provides good wear resistance, chemical resistance, and has excellent light transmission. Nano-diamond films are therefore ideal for many optical windows. The optical glass coated with nano-diamond films can be used to improve the lens' ability to resist rain and sand under extreme conditions.
Even though nano-diamond has many applications and excellent performance, there are still many areas that need to be explored, including biomedical engineering and environmental protection. There are many technologies and applications that must be addressed before there can be any related products. According to product maturity, market acceptance, and cost performance, the most reliable applications still lie in ultra-precision polishing, lubricants, or composite coatings.
