Technological Progress Path of Gem-Quality Synthetic Diamond by MPCVD

MPCVD is favored for its stable energy input, high process control, and excellent growth quality, demonstrating high performance in growing large, high-purity, well-coloured gem-quality diamonds. Reviewing the development in growth mechanism, methods and related results of MPCVD technology in recent three years, we noted advancements focus on producing large single-crystal diamonds, reducing non-diamond phase, enhancing purity, optical quality and color-performance, and achieving balances between growing speed and quality by adjusting the growth parameters. The development of MPCVD technology of growing gem-quality diamonds has promoted the overall development of MPCVD technology and will help to further expand the research and implementation of industrial applications.
