The structure of graphite crystal is a repetitive pattern. This pattern gets disrupted at the surface of the crystal and leads to what's called 'surface states', which are like waves that slowly fade ...
Synthetic graphite is made by subjecting amorphous (non-crystalline) carbon to enormously high temperatures to rearrange the carbon atoms into the proper crystal structure. Choice of feedstock is ...
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 ...
