Application of super conductors 1) It is a basis of new generation of energy saving power systems. Super conducting generators are smaller in size and…

Amorphous solids possess properties of incompressibility and rigidity to a certain extent but they do not have definite geometrical forms. When certain liquids are cooled…

Frenkel defects arises when an ion occupies an interstitial position between the lattice points. This defect occurs generally in ionic crystals in which the anion…

Point Defects in a Crystal: Almost all the crystals encountered in practice suffer from imperfections or defects of various kinds. An ideally perfect crystal is…

Schottky defects in a Crystal Almost all the crystals encountered in practice suffer from imperfections or defects of various kinds. An ideally perfect crystal is…

Crystalline solids exhibit an important property called conductivity. Conductivity is the property of a material by which it allows the flow of electric current. Conducting…

Metal Deficiency Defects: In certain cases, one of the positive ions is missing from its lattice site and the extra negative charge is balanced by some…

If a crystal of NaCl is heated in sodium vapour, it acquires a yellow colour. This yellow colour is due to the formation of a…

Bragg’s spectrometer method is one of the important methods for studying crystals using X-rays. The apparatus consists of an X-ray tube from which a narrow…

In ionic crystals, the units occupying lattice points are positive and negative ions. Each ion of a given sign is held by coulombic forces of…
