As superhard abrasive material, synthetic diamond micron powder has incomparable superior grinding performance and is highly valued by various industrialized countries. The grinding performance of synthetic diamond micron powder including the grinding force for workpieces and its own resistance to abrasion and pulverization, depends on its microhardness, particle size, strength, particle shape, thermal stability and chemical stability.

In summary, the applications of synthetic diamond micron powder as abrasive grains include three major aspects:
1. For the manufacture of resin bond, vitrified bond, metal bond, and electroplated abrasive tools;
2. Fine grinding or polishing of various precision components used in industry, science and medicine;
3. As fine abrasive grains, used for some mold processing, gemstone polishing, and bearing processing and manufacturing.

In addition to being used as grinding materials, synthetic diamond micron powder is also used as the functional material. For example, we can make full use of its thermal properties and electrical properties to manufacture a new material with improved thermal conductivity and reduced thermal expansion by mixing micron diamond powder into a thermosetting resin polymer, cellulose, phenolic resin or ceramic chip. If mixing diamond micron powder into sheetmetals, such as nickel sheets or stainless steel sheets, a new sheet material can be made with high thermal conductivity, low thermal expansion and light weight, which can be made into high-density and high-energy devices used for thermal control in the electronics industry.

From the form of synthetic diamond micron powder used as grinding material, more than 60% of consumed diamond micron powder in industry is used to make diamond abrasive paste, diamond micron powder mixture and diamond micron powder grinding lapping slurry, according to the figures published in the relevant data.
