The latest test of scientists revealed, hexagonal diamonds are stiffer than natural diamonds

According to scientists from Washington State University, they have created hexagonal diamonds that are harder than natural diamonds. While hexagonal diamonds are nothing new, previous lab-created versions were too small or existed too short to be accurately measured.

Diamonds found in nature are commonly used in jewelry, also known as block diamonds. This gemstone is famous for its durability and thermal conductivity. However, very rare hexagonal, hexagonal diamonds were found until nya.

The inability to measure these unique diamonds raises many questions about their differences from conventional ones. This is what researchers at Washington State University are looking for to answer. The diamonds are made of graphite discs, which are pushed at lightning speed using compressed air and gunpowder. The shock waves then form hexagonal diamonds.

The scientists then used lasers and sound waves to determine the hardness of the hexagonal diamond relative to its natural “cousins”. This process takes place at an amazing rate for a few nanoseconds before the diamonds made in the lab are destroyed by the impact so quickly.

“Diamond is a very unique material. It’s not only the strongest, but it also has very attractive optical properties and a very thermal conductivity,” said study author and director of the Institute of Shock Physics . “Now we have made hexagonal diamonds, which are produced in compression experiments. They are significantly harder and stronger than conventional gemstone diamonds.”

Assuming scientists can one day produce these diamonds without causing them to be destroyed, hexagonal diamonds can be used in a variety of industries, including replacing sheet diamonds. to make super hard blades and drill bits.
