Whether natural or synthetic, diamond powder is a super-hard fine abrasive that is widely recognized internationally. With the development of high technology, diamond powder uses in various industrial sectors are becoming increasingly extensive.
Diamond's grinding capability is 1.25 times greater than that of cubic boron nitride, 2.85 to 3.57 times greater than that of silicon carbide, and 6.25 to 7.14 times greater than that of white corundum. Diamond powder has exceptionally superior grinding capabilities, increasingly attracting the attention of industrially developed countries. The grinding ability of diamond powder includes its capability to grind workpieces and its own resistance to wear and fracture. This depends on its microhardness, particle size, strength, particle shape, as well as thermal stability and chemical stability.
Diamond powder uses mainly for the fine grinding or polishing processing of various precision components in industries, science, and medicine. It is used in the manufacturing of resin-bonded tools, metal-bonded tools, and electroplated tools; as a fine abrasive for mold processing, gemstone polishing processing, and gemstone bearing manufacturing.
Based on certain reported figures, over 60% of the diamond powder consumed industrially worldwide is used to produce diamond grinding paste, diamond powder mixtures, and diamond powder grinding fluids.
For example, utilizing its thermal and electrical properties. Mixing diamond powder into thermosetting resin polymers, cellulose, phenolic resins, or ceramic sheets can create new materials with enhanced thermal conductivity and reduced thermal expansion. Mixing diamond powder into metal sheets, such as nickel sheets or stainless steel sheets, can produce new sheet materials with high thermal conductivity, low thermal expansion, and light weight, which can be used to make high-density, high-energy devices for thermal control in the electronics industry.
Since the mid-1990s, some new developmental trends have emerged in the production of diamond powder.
The particle size classification is becoming finer, and the particle size range is narrowing.
Natural diamond powder continues to develop.
Ultra-high grinding performance diamond powder.
Diamond powder with strict particle size tolerances.
Explosively synthesized diamond powder.
Development of specialized diamond powder.
Diamond powder has a broad future development prospect. Its application in industry and high technology fields will be further expanded. As a key component of high-performance materials, diamond powder uses are expected to continue to expand, bringing more innovation and progress possibilities to various industries. The potential applications of diamond powder in electronics, medicine, and energy fields are enormous, indicating that it will become one of the important pillars of future technological innovation.
