Ultra Detonated Polycrystalline Diamond Powder
Polycrystalline diamond powder is a nano-diamond polymer synthesized by transient ultra-high pressure and high temperature explosion, which is similar to the black diamond found in a small number of meteorites in nature. It is a polycrystal composed of cubic diamond and hexagonal diamond. It has the characteristics of high toughness, high self-sharpening and high hardness. As a new type of abrasive material, it has the irreplaceable advantages of other materials in sapphire grinding and processing. The grinding efficiency is 2 to 4 times that of single crystal diamond, and it does not produce scratches, and has a high finish. It has a wide range of applications in high-tech fields such as electronics, aerospace, and aviation. Due to the continuous expansion of the application fields of new technologies in industries such as LEDs in recent years, the use of polycrystalline diamond powder has increased significantly, and the demand has continued to increase.
