Yesterday 04 may 2021 (sciencedaily.com) - Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in nature and often used in jewelry. Named for their six-sided crystal structure, hexagonal diamonds have been found at some meteorite impact sites, and others have been made briefly in labs, but these were either too small or had too short of an existence to be measured. Now scientists at Washington State University's Institute for Shock Physics created ...

Diamonds are the strongest material on Earth, but an even stronger type of diamond has been created in the lab. Hexagonal diamonds are stiffer and stronger than the typical cubic diamonds used for jewelry, according to WSU researchers. Both graphite and diamonds are made of carbon, and this allows graphite to be converted to diamond under extreme compression, said Yogendra Gupta, professor at the WSU Institute for Shock Physics and co-author in the study. To convert the graphite into diamond, a small graphite disk was accelerated through a two-stage gas gun, said lead author Travis Volz, who ...
