In 2013, a research team at the Ningbo Institute of Materials Technology and Engineering began researching technologies related to industrial diamond production.

After years of exploration, they independently developed a microwave plasma chemical vapor deposition (MPCVD) system for single crystalline diamond growth, thus achieving CVD single crystalline diamond industrial production via domestic equipment for the first time.

The team has developed the preparation equipment and process for 12-inch large-area diamond growth with independent intellectual property rights, and established the first CVD single crystalline diamond production line in China with annual output capability exceeding two million carats, ranking top three in the world.
