WebJul 25, 2016 · CVD stands for chemical vapor deposition and is another method used for making diamonds in a lab. Diamonds grow from a hydrocarbon gas mixture subjected to moderate pressures and temperatures in a vacuum chamber. The CVD Diamond Growth Process Diamond seed crystals are placed in a diamond growth chamber. WebNov 8, 2024 · Chemical Vapor Deposition Similar to PVD in that it is used to produce high-purity, specialized thin coatings, CVD involves mixing the source material with one or more volatile precursors that functions as a carrier device. These precursors, which are typically halides or hydrides, chemically interact and break down the source material.
