Microwave plasma for Lab-Grown Diamond (PE-CVD)
Synthetic diamond: jewelry & technical applications
Chemically identical to natural diamond, synthetic diamond is making its mark in two fields: jewelry, where it offers pure, ethically sourced gemstones, and high-tech industry, where its unique properties — hardness, thermal conductivity, optical transparency — make it an unrivalled material.
Microwave technology & PE-CVD process
Microwave plasma PE-CVD is the benchmark process for producing the highest-quality lab-grown diamonds. Microwave energy generates a stable, electrodeless plasma that enables contamination-free crystal growth with precise, reproducible process control.
Key advantages of microwave plasma
Homogeneous and stable plasma
Our technologies generate highly uniform plasma, ensuring consistent treatment conditions and improved process repeatability.
High ionization efficiency
High ionization density enables enhanced reaction kinetics, optimized yields, and improved process performance.
Scalable multi-source architecture
Multi-source integration enables wide and uniform plasma distribution, supporting large-area processing and seamless industrial scale-up.
Efficient power transfer
Direct energy coupling minimizes power losses, ensuring high energy efficiency and stable plasma generation
Everything You Need to Know: How Sairem’s microwave plasma generators enhance CVD lab-grown diamond production
The architecture of our 2450 MHz generators is 100 % digital. They have been developed to support weeks-long running cycles and to deliver a stable and narrow spectrum, to fit your industrial or R&D applications perfectly. The built-in Auto Restart Function (ARF) automatically resumes operation after any unexpected interruption, minimising production downtime and protecting long-duration growth cycles — a critical feature for unattended industrial processes.
