Discover industrial-grade CVD diamond machines manufactured by MARS IMPEX. Utilizing advanced Microwave Plasma Chemical Vapor Deposition (MPCVD), our systems deliver 10 to 35 μm/hr single-crystal diamond growth for luxury gemstone jewelry, semiconductor heat sinks, and precision optical windows.
A CVD diamond machine synthesizes authentic diamonds under low-pressure vacuum conditions by decomposing carbon-containing precursor gases inside an ionized plasma cloud.
Methane (CH₄) supplies the elemental carbon, while ultra-pure hydrogen (H₂) acts as the carrier gas and selective etchant. Guided by high-frequency 2.45 GHz or 915 MHz microwaves, the energetic plasma breaks molecular bonds, allowing pure carbon atoms to crystallize onto diamond seed substrates in perfect tetrahedral lattice formations.
Zero metallic flux contamination. Clean DEF color and eye-clean VVS/VS clarity.
Optimized growth rates ensuring high carat output with low defect density.
