Question

what are the difference between schottky defect and frankel defect​

Answer 1

Answer:

In Schottky defect, both cation and anion leave the solid crystal. In Frenkel defect, only the smaller ion (cation) leaves its original lattice site; whereas, the anion remains in original lattice sites. The atoms permanently leave the crystal.

Answer 2

⭐ $\sf\underline\pink{ Schottky~~defect}$ :- The missing of an ion from crystal lattice accompanied by missing of oppositely charged ion is known as schottky defect.

• Schottky defect is a point defect.
• Ex :- NaCl , KCl , AgBr

⭐ $\sf\underline\green{ Frenkel~~defect}$ :- Frenkel defect is due to dislocation of constituent particle from lattice point to interstitial site.

• Frenkel defect is a dislocation defect.
• Ex :- AgCl , AgBr , AgI
