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.

Compared to other forms of synthetic diamond, single crystal diamond CVD has a highly ordered crystal structure, which gives it improved physical and mechanical properties. This makes it a desirable material for a range of high-performance applications, where its hardness and thermal conductivity are important factors.

In summary, single crystal diamond CVD is a type of synthetic diamond that is produced using the CVD process and is characterized by its exceptional hardness and thermal conductivity. It has a wide range of applications in industries such as manufacturing, electronics, and optics.

Polycrystalline CVD Diamond

Chemical Vapor Deposition (abbreviated as CVD) is the use of gaseous or vaporous substances in the gas phase or gas-solid interface reaction to generate solid-state deposit process. Under low-pressure conditions, a certain method is used to activate the carbon containing gas, so that the carbon atoms therein are supersaturated on the substrate (seed crystals) to deposit and grow into diamond. The activation of the carbon source gas and the deposition of carbon atoms are accompanied by a series of chemical reactions, so this method of synthesizing diamond is called chemical vapor deposition.
