According to the provisions of the current national standard GB/T 7990-1997, diamond powder with a particle size equal to or finer than 54 μm is called diamond powder.
It has three main applications.
First, it can be directly used or made into abrasive paste for free grinding or polishing. It is used to process precision parts or special-shaped workpieces such as cutting tools, measuring tools, optical instruments, and electronic devices made of materials such as cemented carbide, glass, ceramics, gemstones, and diamonds, and can achieve a mirror finish.
Second, it is used as a raw material for manufacturing large-grained polycrystalline diamonds.
Third, plating micron powder on the surface of certain workpieces can increase their wear resistance. For example, plating a layer of diamond micron powder on the surface of molds, machine tool guide rails, bearings or other steel workpieces can increase their surface hardness, reduce the friction coefficient, and double the wear resistance.
In addition, micron powder can sometimes also be used to manufacture electroplated abrasives for grinding.
The raw materials for manufacturing diamond micron powder can be divided into natural diamond and synthetic diamond. And there are three methods for the production of synthetic diamond micron powder: First, the commonly used crushing method (or mechanical crushing method); second, the explosion method; and the third is the static pressure direct growth method. Explosion micron powder is most complete in the products of DuPont Company in the United States. Japan, Germany and the Soviet Union also produce it, but the output is very small. The mechanical crushing method is a method widely used at home and abroad. The static pressure direct growth method has received attention in recent years and is under development.
