In three-dimensional space there are 14 Bravais lattices. These are obtained by combining one of the seven lattice systems with one of the centering types. The centering types identify the locations of the lattice points in the unit cell as follows: (1) Primitive: lattice points on the cell corners only (sometimes called simple) (1) Base-centered: lattice points on the cell comers with one additional point at the center of each face of one pair of parallel faces of the cell (sometimes called end-centered) (7) Body-centered: lattice points on the cell corners, with one additional point at the center of the cell (2. Face-centered: lattice points on the cell comers, with one additional point at the center of each of the faces of the cell. Write the axial lengths and axial angles of the seven lattices systems and draw the 14 possible Bravais lattices. For example: 1- Cubic systems The following relation can be observed Lattice constants (parameters) a=b=c== The 3 possible types of cubic cell are illustrated below
