Product Description
Excellent thermal conductivity
Low frictional coefficient and thermal expansion coefficient
Low dielectric constant
One of many remarkable properties of diamond is its unsurpassed thermal conductivity. It exceeds that of copper by a factor of five. In contrast to metals, where heat is conducted by electrons, lattice vibrations are responsible for the high thermal conductivity of diamond.
The thermal conductivity of optical quality CVD diamond which made by our Laboratory through DC arc plasma jet approaches that of natural type IIa diamond, 1800W/mK. Thermal conductivity can be tailored within the range of 1000-1800 W/mK to enable matching cost/performance to the needs of the application.
Nowadays CVD diamond made by our Laboratory is used as mounts for high-power integrated circuits and laser diodes.
