The cubic structure of NaCl is not a mere coincidence ... where the interplay of natural forces creates both the striking ...

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 ...

This uncanny regularity, a rarity in naturally occurring structures ... The seven main crystal systems—cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, and triclinic—describe ...

The material withstands 58 percent more stress than diamonds, and could have "remarkable mechanical properties".

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 ...
