Soviet scientists had discovered that nano-diamonds powder was possible from carbon-based explosives-caused nuclear explosions. The detonation process has been used to create this promising material since 1963.
Synthesis – nano-diamond crystal powder using detonation method
Hydrothermal synthesis and ion bombardment are all possible methods to obtain nano-diamond crystal powder, however, they have slower reaction times, less energy, and lower efficiency. The detonation method has been renamed nano-diamonds. This method is used in industrial production.
A nano-diamond powder is synthesised by means of detonation. It has an excellent production efficiency. A high explosion temperature and high pressure will cause the carbon component of an explosion to become diamond. A nano-diamond-containing black powder, which is thermodynamically stable, is prepared by this method.
A process that produces gray nano-diamonds powder from black powder has been developed. It is possible to recover between 8 and 10% of the explosive mass, with a diamond particle size of 5-10nm. Following chemical purification, it is around 95-97% pure.
Nanodiamond powder application:
Nanodiamonds possess unique properties that make them useful for precision polishing or lubrication, chemical catalyst, composite coatings as well as high-performance metal composite materials.
A variety of Nano-diamond powder polishing pastes/suspensions are used for medical, pharmaceutical, manufacturing and gemstone industries. The advantages of the nano-diamond powder polishing pastes and suspensions are that they can create a mirror effect over any solid. Also, Ra is high enough to allow for a 2 – 8 nm surface roughness.
Nano-diamond oil can transform sliding friction into rolling friction by adding it to the lubricating olefin. The friction couple’s surface is slowly changed to produce hard and smooth metal carbides. They have an anti-friction effect and anti-wear that is incomparable to organic chemical approaches. This can help improve the engine’s and transmission life and reduce fuel consumption.
Nano-diamond has super-hard particles and the double properties of powder. It can be used for reinforced rubber production and reinforced resin. This plays a major role in improving the material’s thermal conductivity. Nano-diamond’s potential for future development is great in the area of new composite material.
Excellent optical properties include excellent light transmittance, high reflectance index and wear resistance. It is therefore an ideal material for many optical windows. Nano-diamond protective coating on optical glass can greatly improve optical lenses’ resistance to rain, dirt, and scratches.
Although nanodiamond powder can be used in numerous applications and has excellent performance, it is still being explored in many fields like environmental protection engineering and biomedical. Although the prospects and value of nano-diamond powder are excellent, there are still too many technology issues to solve and it is unlikely that there will soon be any related products. These are areas that have the highest market maturity, performance, and recognition in terms of quality and price, such as ultra-precision Polishing, Lubricants, or Composite Coatings.
