Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

By subjecting graphite to extreme pressure and heat, researchers synthesized a rare hexagonal diamond, also known as lonsdaleite—a crystal structure that has long been theorized to be stronger ...

Its atomic radius is 0.160nm and the (+4) ionic radius is 0.080 nm. In the solid state Zirconium has a hexagonal-close-packed crystal structure Zirconium has a Young's modulus of 99 GPa, a yield ...

Aluminum nitride (AlN) and silicon carbide (SiC) are both high-performance engineering ceramic materials, but there is a ...

and the University of Montpellier have successfully synthesized wafer-scale hexagonal boron nitride (hBN) exhibiting an AA-stacking configuration, a crystal structure previously considered ...
