Overview

Tetrahedral voids are essential components of crystal lattices, where they provide spaces for atoms to occupy, influencing the overall structure and properties of materials. Understanding these voids helps in various fields, including material science and nanotechnology, as they affect conductivity,...

Key Terms

Crystal
A solid material whose atoms are arranged in a highly ordered structure.

Example: Salt is a common example of a crystal.

Lattice
A regular arrangement of points in space representing the positions of atoms in a crystal.

Example: The cubic lattice of sodium chloride.

Tetrahedron
A three-dimensional shape with four triangular faces.

Example: A pyramid with a triangular base is a tetrahedron.

Coordination Number
The number of atoms or ions immediately surrounding a central atom in a complex or crystal.

Example: In a tetrahedral void, the coordination number is four.

Packing Efficiency
The fraction of volume in a crystal structure that is occupied by atoms.

Example: Higher packing efficiency leads to denser materials.

Octahedral Void
A type of void in a crystal lattice surrounded by six atoms.

Example: Octahedral voids are larger than tetrahedral voids.
