(SCIENCE ALERT) – Natural diamonds take billions of years to form in the extreme pressures and temperatures deep underground. Synthetic forms can be produced far quicker, but they typically still require some intense squishing for up to several weeks. A new method based on a mix of liquid metals can pop out an artificial diamond in a matter of minutes, without the need for a giant squeeze.
While high temperatures were still required, in the region of 1,025°C or 1,877°F, a continuous diamond film was formed in 150 minutes, and at 1 atm (or standard atmosphere unit). That’s the equivalent of the pressure we feel at sea level, and tens of thousands of times less than the pressure normally required.
The team behind the innovative approach, led by researchers from the Institute for Basic Science in South Korea, is confident that the process can be scaled up to make a significant difference in the production of synthetic diamonds.
