Single Crystal CVD Plate Description
Chemical vapor deposition (CVD) refers to the gas-phase reaction at high temperature, such as the thermal decomposition of metal halides, organic metals, hydrocarbons, hydrogen reduction or chemical reaction of its mixed gas at high temperature to precipitate metal, oxide, carbide and other inorganic materials. This technology is characterized by: high melting point material can be synthesized at low temperature; The morphology of precipitated materials is single crystal, polycrystalline, whisker, powder, film and so on. It can be coated not only on the substrate, but also on the surface of powder. Especially, high melting point materials such as single crystal diamond can be synthesized at low temperature.
Microwave plasma chemical vapor deposition (MPCVD) is an important method for the preparation of single crystal diamond. In the process of single crystal diamond growth by MPCVD, the single crystal diamond substrate is directly placed in the microwave plasma chemical vapor deposition equipment for growth. Due to the high edge temperature of single crystal diamond substrate, polycrystals will be generated at the edge during the growth process, With the development of diamond growth, polycrystals at the edge will gradually invade the surface of single crystal diamond, and then reduce the effective area of single crystal diamond. After the completion of diamond growth, polycrystals around the diamond need to be removed, resulting in a lot of waste of single crystal diamond. Therefore, it is very important to avoid the appearance of polycrystalline diamond in the growth process for the growth of gem grade large-size single crystal diamond.

Single crystal CVD diamond Introduction
Natural diamonds are created by nature and are the result of high temperature and pressure formed over billions of years. The Lab Grown Diamonds are produced in the laboratory, usually in a few weeks. The chemical difference between the two is same.
So how do you distinguish between Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the Lab Grown Diamonds and natural diamonds. Even professional gemologists need special equipment to identify them. By zooming in, professionals will be able to discern subtle contrasts in diamond inclusions grown and mined in the laboratory.
