How are synthetic diamonds used in industrial tools and abrasives?

Synthetic diamonds are highly valued in industrial applications due to their extreme hardness, high thermal conductivity, and electrical resistivity. Because the synthesis process is costly, most synthetic diamonds are produced as grit or small crystals rather than large gemstones.12

In industrial settings, these materials are utilized in several key ways:

• Abrasives and Coatings: Synthetic diamond grit is used to provide hard, durable coatings for equipment such as grinding wheels, quarrying saws, and mining drills. They are also employed in the polishing of gemstones and other hard materials.13
• Cutting and Machining: Diamond films and crystals are used in cutting tools for high-speed finishing cuts on hard or abrasive materials, as well as for finish-boring specific metal bearings.14
• Precision Tools: Synthetic diamonds are essential for truing grinding wheels and are used in wire-drawing dies.14

Additionally, in high-pressure physics, gem-quality diamonds are used in diamond-anvil cells, which allow researchers to observe materials under extreme pressure and temperature conditions due to the diamond's unique strength and transparency to various forms of radiation.3
