Using a diamond to cut glass is not news, but a research team in northern China recently developed the world’s hardest glassy material that can leave a deep scratch on the surface of a diamond with ease.
The (tentatively named) AM-III, a transparent, somewhat yellowish material made entirely of carbon, reached 113 gigapascals (GPa) in a Vickers hardness test.
In comparison, a natural diamond stone usually scores 50 to 70, with some man-made pieces topping at 100 GPa.
Though mass production could be years away, and the price is unlikely to be cheap, a bulletproof window made with the AM-III could be 20 to 100 times tougher than some mainstream products currently in use.
