It melts at 3727 C. The stable form of carbon at room temperature is Graphite which has a hexagonal crystal structure. (Top diagram) Diamond is metastable at room temperature and has a diamond cubic ...

Thanks to the crystal structure of diamonds, with carbon atoms arranged into a lattice-like structure, diamond is top of the ...

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 ...

The defining feature of this diamond is its hexagonal crystal lattice, distinct from the usual cubic structure seen in natural diamonds. Scientists had suspected for decades that a hexagonal ...

Natural diamonds have a cubic crystal structure, and while six-sided or hexagonal diamonds have been found rarely in nature (like at the site of meteorite impacts), creating them in a lab has ...
