Diamonds, particularly synthetic or lab-grown diamonds, play a critical role in various industrial applications due to their exceptional physical and chemical properties. These properties include extreme hardness, high thermal conductivity, chemical inertness, and optical transparency. Industrial diamonds are primarily used in cutting, grinding, and polishing tools, as well as in advanced technologies like high-energy physics research, electronics, and quantum computing. Synthetic diamonds, which account for 98% of industrial-grade diamond demand, are preferred for their superior and consistent properties compared to natural diamonds. Their applications span across machining, thermal management, optical systems, and even medical technologies, making them indispensable in modern industrial processes.
