It has extremely large crystallographic planes and can approach a single crystal structure. Generally, PG’s mechanical, thermal, and electrical properties are far superior to conventional hexagonal ...

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 ...

1), the material structure resembles a forest of long ... This general rule also operates at the atomic scale: diamond and graphite are made of carbon atoms but their distinct atomic arrangements ...
