Audited Supplier Lab MPCVD System MPCVD Diamond Growth with 2450Mhz Microwave Source
The trend in lab grown diamonds (LGD) is the use of MPCVD (microwave plasma CVD) equipment, which grows diamonds artificially by volumizing carbon (C) on a substrate. It is said to be currently capable of producing 20-carat diamonds. when CH4 and H2 are mixed and excited by microwaves, a glow discharge occurs in a vacuum vessel. Molecules of the reactant gases are ionized and a plasma is generated.
In its CVD process, TN's high-quality gas flow control technology, pressure monitoring product and pressure control solution are used. TN solutions ensure consistent quality diamond growth.
