JCB JPDM polycrystalline diamond micro powder is a nano -diamond polymer that is synthesized by transient ultra -high pressure and high temperature explosion. It is a black diamond stone found in a small amount of meteorite in nature. It is a polycrystal composed of cubic diamond and six -way diamond stone. It has the characteristics of high toughness, high self -sharpness and high hardness. As a new type of grinding material, it has the advantages of other materials in terms of sapphire grinding processing. It is 2 to 4 times, and it does not produce scratches. It is highly smooth and has widely used in high -tech fields such as electronics, aerospace, and aviation.
Polycrystalline diamond micro-powder is a nano-diamond aggregate synthesized through transient ultra-high pressure and high-temperature explosion, similar to the black diamond found in a few meteorites in nature. It is a polycrystalline material composed of cubic diamond and hexagonal diamond, characterized by high toughness, high self-sharpening ability, and high hardness. As a new type of abrasive material, it has unique advantages in sapphire grinding and processing compared to other materials. Its grinding efficiency is 2 to 4 times higher than that of single-crystal diamond, and it does not produce scratches, resulting in high surface finish. It has wide applications in high-tech fields such as electronics, aerospace, and aviation.

Due to the continuous expansion of new technology applications in industries such as LED in recent years, the usage of polycrystalline diamond micro-powder has increased significantly, and the demand has continued to grow.
A. Polycrystalline diamond micro-powder synthesized through explosion has a polycrystalline structure similar to the expensive and rare black natural diamond, exhibiting a dark gray color, metallic luster, good toughness, and automatic edge-forming characteristics.
B. Compared to shock-synthesized static pressure or natural single-crystal diamond, silicon oxide, corundum, and other abrasives, the grinding efficiency of polycrystalline diamond is 2 to 4 times higher.
C. The grinding accuracy of polycrystalline diamond has been unprecedentedly improved.
a. When using 2 to 4 μm polycrystalline diamond powder for grinding, Ra < 1.6 nm.
b. When using 0 to 0.5 μm polycrystalline diamond powder for grinding, Ra = 1.3 to 1.4 nm.
c. When using 0 to 0.125 μm polycrystalline diamond powder for grinding, Ra < 0.1 nm.
D. Due to the "globular" shape on the surface of polycrystalline diamond, the surface of the workpiece being grinded is not prone to scratches, thereby improving the yield of grinding.
E. Polycrystalline diamond micro-powder can also be coated on the inner wall of workpieces (such as cylinders) through chemical coating methods, and its wear resistance is superior to any other material.
Applications of Polycrystalline Diamond Micro-powder:
A. Polishing sapphire, silicon, ceramics, metals, etc.
B. Processing magnetic head materials, anti-magnetic films (MR), multilayer films, sputtering films, molecular beam epitaxy (MBE), ferrite, and printed boards.
C. Processing optical fiber connectors, laser rods, and other products that require a certain degree of light wave transmission.
