11x11x0.3mm Lab Grown Diamond Rough Cvd Diamond Wafers Diamond Plates Cvd Diamond Seeds
Product description:
Single crystal diamond CVD (chemical vapor deposition) refers to a type of diamond that is produced using the CVD process. In this process, a mixture of carbon-containing gases is decomposed under controlled conditions, resulting in the formation of a single crystal diamond layer on a substrate.
Single crystal diamond CVD is known for its exceptional hardness and thermal conductivity, which makes it useful for a range of industrial and scientific applications, such as cutting and grinding tools, heat spreaders, and optical components.

CVD single crystal diamond properties:
Since CVD diamond does not contain any metal catalysts, its thermal stability is close to that of natural diamond. Like high temperature and high pressure artificially synthesized polycrystalline diamond, CVD diamond grains are also arranged in disorder, without brittle cleavage planes, so they are isotropic.
