Many materials crystallize in a regular array with basic building blocks being at repeated regular intervals. The structure is determined by the bond character and energy minimization. Metals, ceramics, polymers can all form crystal structures. Properties are dependent upon the type of bond and the structure. Chapter 3 Crystal Structures
