Question

How many bravais lattice are there ?

Answer 1

there are 14 possible Bravais lattices in three-dimensional space. The 14 possible symmetry groups of Bravais lattices are 14of the 230space groups.

Answer 2

Bravais Lattices

1) How many types of Bravais lattices are there ?

A: There are 14 types of bravais lattices are there through experimentally that it exists.

1. Cubic – 3 bravais lattices – Simple, Face and Body
2. Tetragonal – 2 bravais lattices – Simple, Body
3. Orthorhombic – 4 bravais lattices – Simple, Face, Body and End
4. Monoclinic – 2 bravais lattices – Simple, End
5. Hexagonal – 1 bravais lattices – ( Either corner, body, face or end )
6. Triclinic – 1 bravais lattices – Simple
7. Rhombohedral – 1 bravais lattices – Simple

So, there are 14 bravais lattices of : 3 + 2 + 4 + 2 + 1 + 1 + 1 = 14.
