How are industrial diamonds produced using carefully controlled explosives?

Industrial diamonds are produced using explosive-shock techniques, a process that utilizes the intense energy released by the detonation of chemical explosives to transform carbon into diamond.12

In this method, the carefully controlled action of explosives is applied to carbon-containing materials. When an explosive is detonated, it generates a high-velocity shock wave that induces extreme pressure for a very short duration—typically on the order of a microsecond. This rapid, intense compression forces the carbon atoms to undergo a polymorphic transformation, resulting in the formation of microcrystalline diamond powder.32

While other methods, such as the high-pressure high-temperature (HPHT) process, are more common for producing larger industrial-grade crystals, explosive-shock synthesis remains an important tool for creating fine diamond grit. This material is primarily utilized for industrial applications, including the polishing of gemstones, the creation of hard coatings for machine tools, and the manufacturing of various abrasive products.123
