In a groundbreaking discovery, scientists in Korea have developed a new method to create synthetic diamonds using liquid metal at high temperatures and low pressure. This innovative approach could revolutionize the production of synthetic diamonds, which currently require intense pressure for weeks.
Research conducted by a team of scientists at the Korean Institute of Basic Sciences, published in the journal Nature on April 24, highlights the potential of this new method. By mixing liquid metals such as gallium, iron, nickel, and silicon, the team was able to reduce the pressure required to grow diamonds.
The process involves dissolving carbon into liquid metal and allowing carbon atoms from methane to penetrate the molten metal and act as diamond “seeds.” After just 15 minutes, small pieces of diamond crystals protrude from the surface, and after 150 minutes, a continuous diamond film is formed. The team plans to improve the process further and explore its potential in combination with other liquid metals for even better results.
While still in its early stages, this research shows significant promise for transforming synthetic diamond production. By reducing pressure requirements and enhancing the process, scientists hope to make significant advancements in this field.
