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. Specifications Tolerance of Thickness: ±25um
