The Science of Crystals or, Crystallography represents the nature of a crystal and mostly their Atomic Structure, is very crucial for most of the practicing Scientists whose research work relates with materials and their structures. For instance, Crystallography or, Crystal Structure is being used by Chemists to discover and synthesized new chemical compounds and to change its physical properties. Crystallography is used by most of the Pharmaceuticals and drug discovering companies to make useful modifications in drugs. In addition, Crystallography helps to research into how drugs target proteins, the molecules that are essential for living organisms to function properly. Materials Scientist depends on Crystallography to study new materials having many Industrial applications. Crystals of Lithium niobate are used in the telecom markets.

Crystallography is a scientific discipline in its own right. Similarly, Crystallographers have their own international union and their own systems of Nomenclature and Notation. Crystallography can be found in all science aspects like Chemistry, Physics, Biology, Materials science and Mathematics, as well as in many industries.
