According tomedia reports, traditional diamonds need to take billions of years to form deep in the Earth, extreme pressure and temperature to provide the right conditions for carbon crystallization, but now scientists are working on a more convenient way to forge these gems. Recently, an international team of researchers has successfully shortened the process to just a few minutes, demonstrating a new technology that can be molded not only quickly but also at room temperature.
While the idea of making diamonds in a few minutes in the lab is appealing to jewelers, rappers, or those who want to solve a problem, that’s not the ultimate goal of this type of research. The artificial version of this material known for its tenacity can be used as a new tool, new protective coating or other industrial equipment for cutting ultra-hard materials.
The latest breakthrough is understood to have been led by scientists from the Australian National University (ANU) and RMIT University, who used a device called a diamond pickaxe. The researchers used the device to create the extreme pressure needed to produce super-hard materials. The team applied the equivalent of 640 African elephants to the top of a ballet shoe, which could trigger an unexpected reaction in the device’s carbon atoms.
“The turning point in the story is how we put pressure on it,” says Jodie Bradby, a professor at the Australian National University. We believe that this allows carbon atoms to move to the right position to form heterocligraphite meteorite diamonds and conventional diamonds. “
Among them, conventional diamonds may be found on the engagement ring, while six-way meteorite diamonds are relatively rare and are found only at the site of the meteorite impact. Using advanced electron microscopes, the team examined the samples in detail and found that the materials were formed in strips similar to diamond “rivers”.
Professor Dougal McCulloch, of the Royal Institute of Technology, said: “Our photographs show that conventional diamonds form only in the middle of these hetero-crystalline meteorite diamonds under a new approach developed by our cross-agency team. It’s amazing to see these small ‘rivers’ of six-square-crystal meteorite diamonds and ordinary diamonds for the first time, and it really helps us understand how they form. “
The team hopes the technology will allow them to produce large quantities of man-made diamonds, especially hetero-crystalline meteorite diamonds. It is predicted that the hardness of the six-way crystalline meteorite diamond is 58% higher than that of ordinary diamonds.
Bradby said: “Six-way meteorite diamonds have the potential to cut ultra-solid materials in mines. “
The study has been published in Small.
