*aka ‘crystalline solid’*
.
(a “crystal” is defined by ‘shapely order’ in all 3 dimensions)
.
*non-crystals* –>
“glass”
.
*a crystal is a ‘solid material’ whose constituents (such as [atoms / molecules / ions]) are arranged in a highly ordered microscopic structure, forming a ‘crystal lattice’ that extends in all directions*
.
(in addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations)
(the ‘scientific study’ of crystals and crystal formation is known as ‘crystallography’)
(the process of crystal formation via mechanisms of crystal growth is called ‘crystallization’ or ‘solidification’)
(the word crystal derives from the ancient greek word κρύσταλλος (krustallos), meaning both “ice” and “rock crystal”, from κρύος (kruos), “icy cold / frost”)
(examples of ‘large crystals’ include ‘snowflakes’, ‘diamonds’, and ‘table salt’)
(most ‘inorganic solids’ are not ‘crystals’ but ‘poly-crystals’, i.e. many microscopic crystals fused together into a ‘single solid’)
(examples of ‘poly-crystals’ include most ‘metals’, ‘rocks’, ‘ceramics’, and ‘ice’)
(a third category of solids is amorphous solids, where the atoms have no periodic structure whatsoever)
(examples of ‘amorphous solids’ include ‘glass’, ‘wax’, and many ‘plastics’)
