Most industrial diamonds are used as abrasives. However, diamonds are used in many other applications.

Diamond windows

  are made from thin diamond membranes. They are used to cover openings in lasers, x-ray machines, and vacuum chambers. They are transparent, very durable, and resistant to heat and abrasion.

Diamond speaker domes

  enhance the performance of high-quality speakers. Diamond is a very stiff material, and when made into a thin dome it can vibrate rapidly without the deformation that would degrade sound quality.

Heat sinks

  are materials that absorb or transmit excess heat. Diamond has the highest thermal conductivity of any material. It is used to conduct heat away from the heat-sensitive parts of high-performance microelectronics.

Low-friction microbearings

  are needed in tiny mechanical devices. Just as some watches have jewel bearings in their movements, diamonds are used where extreme abrasion resistance, durability, and reliability are needed.

Wear-resistant parts

  can be produced by coating surfaces with a thin coating of diamond. In this process, carbon is converted into a vapor that deposits diamond on the surface of parts prone to wear.
