Question

Write a note on scotty defect

Answer 1

Answer:

Scottky defect is basically a valency defect shown by ionIC solids In this defect an equal number of captions and anions are missing to maintain electrical neutrality. It decreases the density of a substance. Significant number of Scottky defects are found in ionic solids.

For example- In Nacl, there are approximately 10^6 Scottky pair per cm^3 at room temperature. Ionic substances containing similar sized captions and anions show this type of defect.

Nacl, KCl, CsCl, AgBr etc are some examples of this defect.

Answer 2

Schottky Defect Explanation:

Schottky defect is however different from frenkel defect wherein the atoms permanently leave the crystal in terms of schottky defect while atoms usually stay within the solid crystal in frenkel defect. We will further study the characteristics below.

Characteristics of Schottky Defect

Some distinct characteristics of this defect are;

•There is a very small difference in size between cation and anion.

•Cation and anion both leave the solid crystal.

•Atoms also move out of the crystal permanently.

•Generally two vacancies are formed.

•As for the density of the solid it decreases considerably.
