Researchers Find New Phase Of Carbon, Make Diamond At Room Temperature

Scientists from North Carolina State University have found a new phase of solid carbon, called Q-carbon, which is different from the currently known phases of graphite and diamond. Researchers have also developed a method for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air. Phases are different forms of the same material. Graphite is one of the solid phases of carbon; diamond is another. Jay Narayan said “We’ve now created a third solid phase of carbon. The only place it may be found in the natural world would be possibly in the core of some planets.” Jay Narayan is the lead author of three papers describing the work and currently working at John C. Fan Distinguished Chair Professor of Materials Science and Engineering at NC State.

This newly discovered phase, Q-carbon, has some rare characteristics. For one thing, it is ferromagnetic – which other solid forms of carbon are not. Narayan says “We didn’t even think that was possible,” Furthermore, Q-carbon is even harder than diamond, and glows when uncovered to even low levels of energy. The work is described in two research papers. You can read the whole story here
