CVD Diamond has been recognized an ideal material for various applications because of its outstanding properties which includes extreme hardness and strength, high thermal conductivity, low thermal expansion, excellent dielectric properties, resistance to chemical attack, and optical transmission over a wide spectral range. It can be widely used in complex tooling and machining processes, thermal-management applications, semiconductor industry and microwave engineering.
