The atoms in a crystalline solid are arranged in a regular pattern, called a crystal lattice. This repeating structure gives rise to many of the unique properties of crystalline solids. Some crystalline solids examples include diamonds, quartz, and table salt. Crystals can have certain special electrical, optical, and mechanical properties that glass and polycrystals normally cannot. These properties are related to the anisotropy of the crystal, i.e. the lack of rotational symmetry in its atomic arrangement. One such property is the piezoelectric effect, where a voltage across … See more A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In … See more Crystals are commonly recognized, macroscopically, by their shape, consisting of flat faces with sharp angles.
