Question

Write a short note on schottky and frenkel defect.​

Answer 1

Answer:

Schottky defect occurs in those ionic crystals where difference in size between cation and anion is small. Frenkel defect usually occurs in those ionic crystals where size of anion is quite large as compared to that of the cation. In Schottky defect, both cation and anion leave the solid crystal.
