Polycrystalline CVD diamond
polycrystalline CVD (chemical vapour deposition) synthetic diamond products are manufactured by a chemical vapour deposition (CVD) process and are subject to tightly controlled growth conditions during manufacturing and equally stringent quality control procedures.
CVD Diamond for thermal applications:
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.
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.
