A crystal or crystalline solid is a solid material
whose constituent atoms, molecules, or ions are arranged in an orderly
repeating pattern extending in all three spatial dimensions. The
scientific study of crystals and crystal formation is crystallography.
The process of crystal formation via mechanisms of crystal growth is
called crystallization or solidification. The word crystal is derived
from the ancient Greek word κρύσταλλος (krustallos), which had the
same meaning, but according to the ancient understanding of crystal.
At root it means anything congealed by freezing, such as ice. The word
once referred particularly to quartz, or "rock crystal". |
