Question

What do uh mean by schottky defect?? ?

Answer 1

Answer:

Schottky Defect = The defect in crystal lattice due to the missing number of equal cations and anions from their lattice sites.

The defect produce due to removal of a cation and anion from a crystal lattice.

Crystal lattice = Crystal lattice = Shape of any crystal in which unit cells are arranged systematically and three dimensionally is called crystal lattice.

Answer 2

Schottky defect :-

This type of defect created when one +ve ion and one -ve ion are missing in their respective positions leaving behind a pair of hole .

This defect is also called vacancy defect in ionic solid .

This defect are more common in ionic compounds with high co-ordinate number and size of +ve

and -ve ion must be equal

Example

KCl

NaCl

AgBr

Kbr
