The Structure of Solids |
|||||||||||||||||
· The atomic arrangement in a
solid may control its external shape. Huygens (1690) showed that the shape
of a Calcite crystal could result from the stacking of equal sized spheroids |
|||||||||||||||||
· The external geometry of crystals
tends to show the faces of lowest energy so that the free energy (Gibbs
function) of the crystal is minimized. |
