Crystal lattice

Crystal lattice is a three-dimensional geometric arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter.

The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure. The unit cell completely reflects the symmetry and structure of the entire crystal lattice, which is built up by repetitive translation of the unit cell along its principal axes.

Types of Crystal Lattice[edit | edit source]

There are 14 unique types of crystal lattices, which are classified into seven crystal systems. These include:

Properties of Crystal Lattice[edit | edit source]

The properties of a crystal lattice depend on the type of crystal system and the arrangement of atoms within the unit cell. These properties include:

Symmetry: The arrangement of atoms in a crystal lattice is highly symmetrical. This symmetry is described by the crystal's point group.
Lattice constants: These are the lengths of the cell edges and the angles between them. They are represented by the letters a, b, and c.
Crystal structure: This is the arrangement of atoms within a crystal. It is characterized by its unit cell, a small imaginary box containing one or more atoms, which is repeated in three dimensions to form the crystal.

Applications of Crystal Lattice[edit | edit source]

Crystal lattices have many applications in various fields such as:
