Space Lattices: Definition And Types In Crystalline Materials
Write a short note on the space lattice.
Answer:
There are 14 different combinations of cell structure and atomic arrangement. These combinations are called space lattices.
- A space lattice is a regular, 3-dimensional arrangement of atoms in a space in a crystalline material.
- Several solid-state reactions can occur in a solid substance and it is due to the diffusion of atoms, for example, In Gold-copper alloys, gold, and copper atoms may be distributed randomly in the space lattices leading to disordered lattices.
- This disordered pattern may change to an ordered pattern in which gold atoms occupy the center of the cubic type of space lattice and copper atoms occupy the corner positions in the space lattice.
- This happens due to the movement or diffusion of atoms under the influence of controlled heat treatment.
- In practical terms, this will change the physical properties of hardness, brittleness, strength, and conductivity of a material.
- Casting gold alloys are heat-treated for this very purpose.
