High Hardness CVD Rough Diamond CVD Blanks For Thermal Management

CVD Blanks For Thermal Management


CVD (Chemical Vapor Deposition) Diamond is a mixture of carbon-containing gas and hydrogen at high temperatures and sub-standard atmospheric pressure is excited to decompose to form an active Diamond carbon atoms and deposited on the substrate intergrowth of polycrystalline Diamond.Since CVD Diamond does not contain any metal catalyst, so its thermal stability close to natural Diamond.CVD Diamond grains are disordered, non-brittle cleavage plane, thus showing isotropic.CVD Diamond is widely used in mechanical, microelectronics, thermal, optical, Aerospace, Military, Medical and other fields.Our company mainly produces the following types of CVD Diamond products: CVD Diamond wire drawing die core, CVD Diamond dresser blank, CVD Diamond cutter blank, thermal grade CVD Diamond sheet, optical grade CVD Diamond sheet and other multi-grade CVD products.And can be cut according to user requirements, polishing and other processing.

Product introduction:

At room temperature, the thermal conductivity of the CVD Diamond is five times that of copper, which can satisfy a variety of thermal applications. it is widely used in the production of laser diodes, laser diode arrays, high-power semiconductor devices, Microwave devices and heat sinks for large scale integrated circuits.Our company produces CVD Diamond heat sink, the thermal conductivity of 1200~2000W/K.m,can be single-sided, double-sided polishing and other processing.
