Synthetic diamond - Wikipedia
Polycrystalline diamond (PCD) consists of numerous small grains, which are easily seen by the naked eye through strong light absorption and scattering; it is unsuitable for gems and is used for industrial applications such as mining and cutting tools.
What is PCD (Polycrystalline Diamond) and Where is it Used?
PCD is a synthetic material composed of diamond particles that are sintered together at high pressure and temperature. It has unique properties such as hardness, thermal stability, and chemical inertness, making it ideal for many manufacturing applications.
Polycrystalline Diamond - an overview | ScienceDirect Topics
