What is the importance of studying crystal structures?
The crystal structure and symmetry play a critical role in determining many physical properties, such as cleavage, electronic band structure, and optical transparency.
What are the different types of crystallography?
- Isometric. This system comprises crystals with three axes, all perpendicular to one another and all have equal length.
- Tetragonal. This system comprises crystals with three axes, all perpendicular to one another; but only two are equal in length.
- Orthorhombic.
- Monoclinic.
- Triclinic.
- Hexagonal.
- Formation of Crystals.
Where is Xray crystallography used?
X-ray crystallography is a tool used for determining the atomic and molecular structure of a crystal. The underlying principle is that the crystalline atoms cause a beam of X-rays to diffract into many specific directions (Fig. 2.10).
Why is it important for materials scientists and engineers to understand crystal structures?
The understanding of crystal structures is an important prerequisite for understanding crystallographic defects. Mostly, materials do not occur as a single crystal, but in polycrystalline form, as an aggregate of small crystals or grains with different orientations.
What is the importance of material science?
Materials science is also an important part of forensic engineering and failure analysis – investigating materials, products, structures or components, which fail or do not function as intended, causing personal injury or damage to property.
What is the importance of material science in engineering?
Materials Science and Engineering is a key aspect of most companies the world over. In the race to make things stronger, cheaper, lighter, more functional and more sustainable, the manipulation of materials, their properties and processes is key.
