Crystal Systems
- The diamond crystal structure belongs to the face-centered cubic lattice.
- Crystal systems are sets of point groups and lattice systems.
- Crystal systems are classified into seven categories: triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic.
- Crystals in the same crystal system have similar symmetries.
- Crystal systems with space groups assigned to a common lattice system are combined into a crystal family.
Classification of Crystals
- Crystals can be classified based on lattice systems, crystal systems, and crystal families.
- Trigonal crystal system is often confused with the rhombohedral lattice system.
- The term crystal system is sometimes used interchangeably with lattice system or crystal family.
Lattice System
- A lattice system is a group of lattices with the same set of lattice point groups.
- There are seven lattice systems: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic.
Crystal Family
- A crystal family is formed by combining crystal systems with space groups assigned to a common lattice system.
- Hexagonal and trigonal crystal systems are combined into the hexagonal crystal family.
