Crystal Physics

Crystal physics deals together with the different variations of crystals and their properties. All fabrics differ from one another in their properties as some solids are ductile, some solids are brittle, some are malleable, some are weak, some are strong, some are good conductors of heat and electricity, some are non conductors of electricity and heat and some are magnetic and non magnetic etc. Solid structures make the differences within the properties and the behaviour regarding the solid fabric is related to its structure. Solid structures are classified based structure of atom and following describes the classification based on the crystal structure spot of view. Solids broadly classified as crystalline and amorphous non-crystalline.

In a solid structure the atoms are arranged in standard pattern or systemic pattern are known as crystalline materials. Arrangement of atoms takes a periodically repeating pattern within the crystalline materials. They can be of lone crystalline or in poly crystalline forms. Within the lone crystalline, the solid is completely created of lone crystal and in poly crystalline material, many mini crystals aggregate which are separated by well defined boundaries. Crystalline solids are also created of non metallic crystals and metallic crystals.

Copper, tungsten, aluminium, silver returns below the metallic crystals and the crystalline carbons, germanium silicon, crystallized polymers returns below the non metallic crystals. In the solid fabrics the atoms are arranged in an irregular pattern are called as non crystalline materials. They can be also called as amorphous materials. Important fabrics coming below the amorphous category is glass, plastics and rubber. A crystal is a 3 dimensional solid structures composed of periodic arrangement of atoms in all 3 directions.

Crystal structures indicate the arrangement of atoms in a crystal and from these simple properties of fabrics are understood. Crystallography is a branch of physics which deals together with the properties, structure, external and internal symmetries in a crystal. A crystal is defined as the collections of atoms in 3 dimensions. The atoms within the crystal are taken as spot to learn the crystal structure for convenience. This representation of atoms as points in a crystal in 3 dimensions is called as space lattice or simple lattice.

Space lattice in a 3 dimensional method is defined as an infinite array of imaginary points in space that is every spot has identical two of every other spot within the array. Points in a space lattice are called as the lattice points or lattice websites and these lattice points join with lines are called as lattice lines or lattice directions. Planes containing the lattice points are called as the atomic plane or lattice plane. A crystal structure is formed by the association regarding the atoms and molecules with every lattice point.
