About Nano Diamond Powder
Diamond nanopowder is the most difficult material known. The industrial production of nano-diamonds is carried out under high temperature and high pressure.
What is nano-diamond technology?
Nano-diamond battery (NDB) is a diamond-based high-power α, β and neutron volt battery, which can provide life-long and green energy for a variety of applications and overcome the limitations of existing chemical batteries. NDB behaves like a tiny nuclear generator.
Applications of diamond nanoparticles include its use as a filling component for synthetic materials and polishing agents. Presumably, they can reduce friction in bicycle chain oil. Due to its unique mechanical, chemical, optical and biological properties, diamonds are considered to be used in a variety of medical applications. In addition, recent developments involve the use of diamonds in prosthesis, sensing, imaging, and drug delivery applications.

Why are diamonds so hard?
Every carbon atom has four electrons in its outermost shell. In diamonds, these electrons are shared with the other four carbon atoms to form very strong chemical bonds, thus forming extremely rigid tetrahedral crystals. It is this simple, tightly integrated arrangement that makes diamonds one of the hardest substances on earth.
Diamond nanopowder is gray spherical high surface area carbon. The typical surface area of nano-sized carbon particles is 10 – 45 nanometers (nm), the specific surface area (SSA) is in the range of 30 – 50 m 2 / g, the average particle size is in the range of 75 – 100 nm, and the specific surface area is about 2 – 10 m 2 / g.

Is diamond dust dangerous?
Due to the mechanical abrasion of diamond powder, it may cause eye irritation, serious eye damage and skin irritation. Diamond powder may be inhaled and cause respiratory irritation. Nanodiamonds or diamond nanoparticles are diamonds with a size less than 1 micron. They may be produced by impact events such as explosions or meteorite strikes. Due to its cheap, large-scale synthesis, potential for surface functionalization and high biocompatibility, nanodiamonds have been widely studied as potential materials in biological and electronic applications and quantum engineering.
