CVD Diamonds: Everything You Need to Know Clean

2019-12-30· CVD diamonds are diamonds. How Are CVD Diamonds Made? Growing CVD diamonds relies on a unique and innovative process. In chemical vapor deposition, a thin ‘seed’ diamond is placed inside of a sealed chamber and subjected to high temperatures (generally around 800°C). Then, a carbon-rich gas mixture (usually of hydrogen and methane) is

What are CVD Diamond Made of CVD Diamond

To produce a gem-quality CVD diamond, a diamond seed crystal (natural, HPHT, or CVD in origin) is introduced into the gas mixture, at an elevated temperature of 900 to 1200°C. The activated carbon-hydrogen species travels across the surface of the diamond seed until it finds an available carbon atom, and then attaches itself to this seed atom. The seeded growth is now one carbon atom thicker
