Antiferroelectricity is the process by which a crystal will not exhibit Ferroelectric properties if it has alternating electric dipoles pointing in the opposite direction.
Any deviation from the completely ordered arrangement in a crystal constitutes disorder. Imperfection or defects is employed to denote a departure from the perfectly periodic arrangement of atoms in a crystals.
Crystal or Crystalline Solid …
Crystal possesses a definite geometric shape bound by plane surfaces called Faces.
Hess’s Law of Heat Summation are: (1) The heat of reaction can be calculated using Hess’s Law. (2) Heat changes of very slow reaction can be calculated. (3) The Lattice Energy of a crystal can be determined. (4) Heat of Formation of intermediate products can be calculated.
Seven Crystal symmetric are possible. The seven different combinations of symmetry elements are called Crystal systems.
Upon heating, if the orderly arrangement of ions or atoms in the crystal get displaced and produces electricity then the property of the crystal is termed as Pyroelectricity.
What is a Crystal called?
What is Crystal?
When the crystals, in which the dipoles are oriented in an ordered manner are subjected to mechanical stress or pressure produces Piezoelectricity.
