What is Lattice Structure?

A crystal lattice structure is the three-dimensional arrangement of atoms, ions, or molecules in a crystalline solid, forming a regular, repeating pattern. The smallest repeating unit is the unit cell. There are seven crystal systems (cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, triclinic) and 14 Bravais lattices. The type of lattice structure determines many physical properties of the solid.

Properties & Characteristics

Seven crystal systems based on unit cell dimensions and angles. 14 Bravais lattices. Common types: simple cubic, body-centered cubic (BCC), face-centered cubic (FCC). Coordination number: number of nearest neighbors. Packing efficiency: FCC/HCP = 74%, BCC = 68%, simple cubic = 52%. X-ray diffraction (Bragg's law) reveals lattice structure.

Uses & Applications

Materials science and engineering design. Understanding physical properties (hardness, melting point, conductivity). Pharmaceutical crystal form optimization. Semiconductor device fabrication. Protein crystallography (drug discovery). Ceramic and cement design. Mineral identification.

Safety Information

Theoretical structure — no direct safety concerns. Knowledge of lattice type helps predict material behavior and safety properties.
