Diamond, known as "the hardest substance in nature," has unique physical properties and chemical stability that make it have broad application prospects in many fields. In recent years, diamond micron powder, as a new material, has gradually emerged in the semiconductor industry.Diamond Micropowder refers to diamond particles smaller than 54 microns in size, mainly divided into single-crystal diamond micron powder and polycrystalline diamond micron powder. This article provides an introduction to diamond micron powder.
Single-crystal Diamond Micropowder
Production process: Single-crystaldiamond micron powder is produced by crushing and shaping synthetic diamond single-crystal abrasive grains under static pressure, using special techniques of superhard materials.
Characteristics: Single-crystal diamond micron powder has high output, high hardness, and good wear resistance, making it an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass.
Polycrystalline Diamond Micropowder
Production process: Polycrystalline micron diamond powder is made from graphite using a unique directional blasting method. The shockwave from high-explosive explosives accelerates metal flyers, impacting graphite sheets and converting them into polycrystalline diamond.
Characteristics: The structure of polycrystallinediamond micron powder is very similar to that of natural carbonado diamonds. Its particles are composed of tiny diamond grains bonded by unsaturated bonds, providing excellent toughness.
Diamond micron powder and its products are widely used in automotive, machinery, electronics, aerospace, optical instruments, glass, ceramics, petroleum, geology, and other sectors. Specific applications include:
