Diamond, known for its exceptional hardness and durability, is a mineral composed of pure carbon elements with a tetrahedral spatial structure. As the hardest known natural substance, diamond serves both as a precious gemstone and a critical industrial material for cutting, drilling, grinding, and thermal management applications in the electronics industry.
The superior hardness, thermal conductivity, and electrical insulation properties of diamond make it increasingly valuable in modern high-tech manufacturing. Industrial applications primarily utilize synthetic diamonds, which are produced in significantly higher volumes than natural diamonds.
